Kneel for the help of the master sports teacher! ! ! !

Du fu 1. From your sentence, "once you climb to the top of the mountain, you will see that all the other mountains look short under the sky." I understand your open mind, open mind and lofty aspirations. I understand that standing on the top of the mountain is chic, and the feeling of enjoying the mountain is happy. So from then on, I had the ambition of Lingyun, so in my own heart, I had a confident courage. 2. When the phrase "Worry stops in the south, the hole can't be broken" came to my eyes again and again, it seemed as if a man appeared in front of me, wearing clothes woven with resentment and a sad face. Your footsteps are heavy, your manners are full of depression, and your every expression is full of helplessness and dissatisfaction with the world. It's not yourself that makes you sad. What worries you is not your three meals a day, but the danger of the whole country. Therefore, in my mind, the words "selflessness" and "greatness" have quietly followed you. I sympathize with you, a very talented person, but you can't reuse it. I sigh because your great ambition can't be shown. Since God created you with great talent, why did he let you die in sadness and helplessness? Since you came to this world with extraordinary temperament, why did you die in a hurry just because you were poor? They are all very sad! He was exiled all his life, exiled by life and chased by suffering. Before he could catch the last ray of sunshine in the prosperous Tang Dynasty, he was blown to the river bank rustling in the treetops by the chaotic autumn wind. The emperor and Miyagi have gradually drifted away when they are sideways. Ten years of guest residence, together with the late peony, have been diluted by the rain of the years. When the people's blood and tears finally merged into war, only the stumbling steps between heaven and earth were left, tossing and turning in the broken mountains and rivers. Wandering between hunger and disease, unfolding in the devastation of the journey. The roof of a foreign land is covered with moonlight dew, and he knows that the dew tonight will be frost and autumn grass with white hair. And autumn grass, autumn grass shrinks in a person's thinness. Only the thatched cottage is waiting for him in Shu, and the only habitat in the world will usher in a lonely soul wandering in fate. He is no longer a poet. He is just a husband and father. In his wife's helpless tears, he suffered the great sadness that his young son had just died. And bear the fate, or be manipulated by fate. A person who propped up the dynasty with his body was injured by tiles falling from his class, and a person who loved his motherland all his life was abandoned by his motherland forever. Nothing can be saved, including the tens of millions of luxury houses at the end of the pen, which will also be doomed to collapse. All the tears are poured on a man in rags, but I can't see the glory of an era. Finally, I rely on singing, and finally I get lost in singing. After reading your Delighting in Rain on a Spring Night, I found that your life is full of joy. Yes, you love life and nature, but the dark social world just destroyed your calm heart. The world doesn't allow you to be happy. War does not allow you to live freely. Everything has cut the rope between you and happiness, which is even more sad. You are so far away and so close, you are so mysterious and so ordinary. You end your life with sadness, but you continue your life with poetry. On your life path, sadness and pain make your life path bumpy and prickly, but the mark you left in the history of literature is full of flowers and praise everywhere. Helplessness and resentment destroy your faith in life, but your immortal soul will always be youthful and energetic because of your poems. Qu Yuan 1 and the great poem The Level of the Sea originated from Li Sao. Each of his poems is a full seed. When planted in the soil, a citrus, a violet, a bag of ganoderma lucidum and an orchid will grow. Two thousand years ago, there was a distant fragrance between his sleeves. His poems are bitter with blood/tears, and a drop of lips will make people awake forever/instead of wine/let the turbid world indulge in tragic laughter ... His poems are fire/but they can't burn through the night before dawn, and they are a long trek in the jungle of thorns, winding for a bright exit. He burned his liver and gall into lamp oil, ground it into ink, and wrote down the dark spell of the old times. His poems were ridiculed and even besieged at that time, but now they have become a banner, flying over the human spirit and lifelike. The descendants of the dragon said: the upstream of the blue ink is the Miluo River! 2. "I take a long breath to hide my tears and mourn the hardships of people's lives." Qu Yuan is such a poet who cares about the country and the people. "The world is turbid and I am alone, and everyone is drunk and I wake up alone." Qu Yuan is such a historian with strong belief. "Qingyun is dressed in white and shoots Sirius with a long arrow." Qu Yuan is such a warrior with high morale. "I am also kind. Although I died nine times, I still have no regrets. " Qu Yuan is such a hero who is not afraid of violence. No matter how history changes, no matter how times change. From the moment Qu Yuan jumped into the Guluo River, he was firmly solidified and precipitated in the hearts of Chu people, and it was destined that his soul would be washed and crossed, constantly cut and lingering, and then sublimated into a great national spirit. Today's "Qu Yuan" is not the doctor Qu who was more than two thousand years ago. He represents a spirit of the times, people's complex and national culture that passes through time and space, one after another and passed down from generation to generation. In this way, "Qu Yuan" lived vividly and permanently in the hearts of the people. The sky in Chu is too small for your galloping thoughts. Miluo river is affectionate and embraces your romantic lost soul. The poet is too concerned about the country and the people, too concerned about the country and the people. So anger and sorrow erupted like a volcano, turning into Li Sao, into Nine Songs and into a bloody poem. Heaven and earth have feelings, and all beings listen to your tears; Benefiting the people and having love; Good people sigh that Miluo is lucky, and the lucky Miluo has taken in your soul without habitat. Zongzi on Dragon Boat Festival has been calling for your soul for thousands of years, offering sacrifices to your spirit from a distance. 4, the breeze gently blows up the pages, and it seems to be mixed with a hint of vanilla. My eyes wander between the words written by Sima Qian emotionally, and I read you carefully-Qu Yuan. "Drink Mulan in the morning and watch Qiuju in the evening." Your conduct is as noble as jade, and you will not be contaminated by all the dirty things in the world. I believe that with such high morality, you will inevitably yearn for a quiet and peaceful life. You may be willing to stand by and watch the lake with the white clouds and breeze and listen to the clear springs of the mountains and streams; You may yearn to walk with the small bridge and flowing water, live under the cross gate and walk towards the sound of quiet bamboo; You may prefer to wander with the clouds outside the sky, suffer humiliation and have no intention of staying or staying. When a person is in a desperate situation, the most common choice is to retire from the mountains and become an idle person in a paradise. However, you care about the people of the whole country, but you have not made such a decision. You have Tao Yuanming's detached feelings, but you won't hide in the peach blossom garden of your own spirit like him and enjoy leisure alone; You have the noble character of Lin Hejing's "beautiful wife and crane", but you won't indulge in the small scenery of the mountain garden like him, and waste your life. During the Warring States period, horns sounded everywhere and yellow sand filled the sky. You struggled and stumbled in the stormy weather, but you never fell down. You shouldered the heavy responsibility of defending the country with your thin but powerful shoulders. However, Huang Zhong abandoned it, and the chaotic Chu State was in danger. The fatuous King of Chu listened to rumors and turned a blind eye to your loyalty and wisdom. Your thin body has gradually become overwhelmed. Who can help you at this time? Finally, you should put it on the river, full of tears, and give a sigh that "the world is turbid and I am alone, and everyone is drunk and I am alone". Some people advise you to keep pace with the times and go with the flow, but you use "Ann can win the warmth of the world with a vast white" to safeguard your lofty ambition. "I lost my mind when I was brought to Du Heng by Shi Lan Xi." I know that vanilla is your favorite, because you appreciate its noble character, detachment that does not compete with the crowd, and tenacity that does not bend with the wind. And you are like a herb growing by the lake, swaying slowly in the wind, and a dewdrop shines silently on the green grass leaves, just like when you look back at your old country, your eyes are shining with crystal tears. Heaven and earth feel sorry for you, too. The endless autumn wind by the river wants to wipe away your tears, but it blows your sadness through the torrent of time. Things have changed for several years, and your figure has already disappeared in the dust of history, but when the young Sima Qian is stationed by the Miluo River and looks forward to the future, he will still shed affectionate tears for you. The voice of your resentment is drifting away on the rolling river, but it is sad and strong. Maybe Sima Qian just heard your voice hit him in the heart, so he wrote a history of faith, so that people from generation to generation can listen to your eternal melody with loyalty and nobility. Reading you, let me understand the noble spirit, you let me understand that the noble spirit is not indifference, not escape, the real noble spirit should dare to take responsibility in their own hearts. Love the country, care for the people, and make your nobility extraordinary. It is this extraordinary nobility that makes you like a lotus flower out of water, like a few plums in the corner, leaving you fresh and dry. The breeze faded away, but the smell of vanilla became stronger and stronger. I still read you, looking for your distant figure between the lines covered with tears ... 4. "I am alone in the world, and everyone is drunk and I wake up alone." Even if you are exiled, you will not go with the flow and set off its waves. Miluo River in Tang Tang finally accepted him, but the water in Miluo River was too miscellaneous to wash away its sadness. The Miluo River is too shallow to bury regrets. You are "coming down, your eyes are misty and sad", but you are still "driving away together when you hear the beauty calling" Speak frankly and forcefully in the imperial hall; Trying to reform the aristocratic power in the early feudal period; At the time of national crisis, "knowing how to rule chaos and making clever remarks" all show your great righteousness and wisdom. But very helpless, when a nation declines, a person's strength will always be regarded as a different kind by the "public", so "the thin waist that the king of Chu loves" was ordered: exile. When the King of Chu betrayed Cheng Yan and regretted having him, you realized that "you can think but you can't do it" and lamented that "people's hearts are different from mine". However, due to pure aristocratic blood and mind, when you stand in front of failure, you yell, stamp your feet, accuse and fight, and you get a greater blow and unbearable. Helpless, you brush away the dust and keep yourself white, not reserved, not evasive, not tactical and angry. When someone hurts you, you expose the wound to him without reservation and shout loudly: I want revenge. 5. "Ruman Manqi Xiu Yuan Xi, I am searching up and down." Qu Zi walked out of the long corridor of history, full of lofty spirit and poetic talent, but in a sophisticated society, how can the edges and corners of his personality be preserved? Therefore, in order to be white and face the world clearly alone, Qu Zi chose the road of "tragedy". In the turbulent Miluo River, he washed himself so thoroughly and clearly. But when he forgot the muddy world, did he remember that there were millions of people and their lofty ideals? 6. Emotion is an innate element of human beings, which is vividly displayed in the life of a generation of benevolent sages. They confide their true feelings and lead a full and frank life. Qu Yuan is such a real person. He sang, "Take a long breath to cover up today's tears and mourn the hardships of people's lives." He shouted, "I'm not satisfied. I'm too late to regret it." He took out a courtier's heart and presented it to everyone without affectation or affectation. In the end, his temperament forged his reputation, which will last forever. 7. Qu Yuan, a patriot who "everyone is drunk and I wake up alone" and "the road is long, and I will go up and down for it", "Although I died nine times, I still have no regrets". Facing the divided motherland and the hungry and cold people, as a scholar-bureaucrat, he was helpless and jumped into the surging river, making him a person who could cry for future generations. He found his place correctly. He is a scholar-bureaucrat seeking a happy life for the Li people. Faced with the corruption of the imperial court, he was helpless and had to devote himself to the sea and sacrificed his precious life for the motherland. 8. On the river bank is Qu Zi. Chu sunset dyed the Miluo River red, Zilan slandered, Zheng Xiu was puzzled, and the people were like wanderers, breathing and struggling. Is Qu Zi's persistence useful? I'm afraid he will shake his head and sigh himself. When Chu perished, it was also the moment when his life ended. He put the status of a politician far above that of a poet. "Who can observe with his own body and who is the receiver of things?" Life is not a poet, but the way to die is a poet. Persistence, why can't you listen to "saints don't persist in things" Tao Yuanming 1 and "picking chrysanthemums under the east fence and seeing Nanshan leisurely"? Who among China literati can be so childlike, leaving only chrysanthemums in Nanshan? Tao Yuanming chose the road of seclusion. This road is chic and clear. However, what did Tao Qian do besides drinking and picking chrysanthemums? This may even be something he can't answer. The road of seclusion has been chosen by countless literati in China, but as Mr. Yu said: "The morality of self-improvement leads to the overall immorality." Perhaps the chance of history contributed to a literary monument. But if the road of history is extended forward, can thousands of Tao Yuanming come out? 2. Tao Yuanming, an idyllic poet in Jin Dynasty, is also keen on officialdom and wants to show his ambition in his career. However, when he made the Pengze county magistrate and learned about the darkness of officialdom, he resolutely resigned and retired. "Birds are tired of the ancient forest, and the fish in the pond miss the ancient garden." He still likes the life of "picking chrysanthemums under the east fence and seeing Nanshan leisurely". From then on, he plowed and stayed away from the world. He found his place and realized his life value. Tao Qian leisurely picked chrysanthemums under the oriental salamander and danced with butterflies. Facing Nanshan, Yuan Ming chose to forget the ugliness of officialdom and all the unhappiness he encountered. This is the choice of the soul, the wise choice made by people crossing the river on both sides of the strait, and the wise "ferry". 3. He is a hermit who "picks chrysanthemums under the east fence and sees Nanshan leisurely", an elegant person who "knows the fun of playing the piano, why bother playing the strings" and a farmer who "hoes Dai Yue", right! It's him, Tao Yuanming, who is famous in the literary world for a hundred years. He doesn't want to "bend down and pick up five buckets of rice" and hang it in the countryside. He forgot the frustration of officialdom and the lack of official career, but remembered the wishes of the world and wrote down the sacred place in his heart-Peach Blossom Garden. 4. Stay away from the world, live in seclusion in the countryside and watch the flowers bloom and fall. Tao Yuanming's life is quiet and free, like white clouds in the blue sky and fish scales in the sea. Because of chrysanthemum, his desire for freedom has been bound by the cage of officialdom for too long. No sustenance at all? Choose chrysanthemums! Fresh and elegant, otherwise it's just like his unruly personality. It was Tao Shi who pinned his heart on the chrysanthemum and found the pure land of his own soul. It was also Tao Shi who made the chrysanthemum wear a high-quality and uncontroversial hat. Xiang Yu 1, Xiang Yu, a former overlord of Chu, can't change the fact that Chu was shattered even if he has unparalleled magic soldiers. On the banks of the Wujiang River, it has been surrounded by the enemy, symbolizing the prosperous Chu songs floating in the air, far away and tactfully. At this moment, his unyielding heart began to weaken. Seeing countless brothers lying around him, he was annoyed at his headstrong attitude and regretted burying the good situation of Chu and the lives of his brothers in his own hands. With deep regret, he put the knife rest around his neck. In an instant, blood stained the banks of the Wujiang River, reflecting half the sky. The sunset is like blood, and the songs of Chu are still sad and moving. A giant fell, but left infinite regret for future generations. 2. "Although it is difficult to pull out the mountain, it makes the world angry, but when it is unfavorable, it will not die. What can I do if it doesn't die? What can I do? " Xiang Yu showed some sadness and helplessness in Gaixia Song. In my opinion, he is a polygon full of corners. Even if he is heroic and ambitious, he can only indulge his head when he is under siege. Desolate praise can only be accompanied by rolling Wujiang River. How does he face the elders in Jiangdong? His spirit, his suddenness and his prominence make history afraid of three points. The first emperor who "ordered eight States to go to the same column and swallowed two States to die" disturbed the world all day long. How can he tolerate Xiang Yu's "pulling mountains and shaking the world"? Xiang Yu, one of the leaders of the peasant uprising in the late Qin Dynasty, was born in a general's family in Chu. When he was a child, his family asked the teacher to teach him to read, but he refused to continue learning until he recognized a few. Let him learn fencing again, but it didn't work. Xiang Yu's uncle Xiang Liang was very angry and scolded him for not making progress. Xiang Yu revealed his heart and said, "It is enough to be able to read and write his own name; Fencing can only deal with one enemy, and it is not worth learning. I want to learn the skills to deal with thousands of troops! " So Xiang Liang taught Xiang Yu to learn the art of war, and finally achieved the great cause of Xiang Yu's "overlord of Chu". 4. Looking at you standing on the edge of Wujiang River, you are heroic and full of pride. I believe what people forget is your embarrassment under siege, but what they remember is your lofty sentiments, your generosity and your infatuation. Suicide by throwing yourself into the river is caused by your generosity, so people will only remember your generosity, and your reputation as a "ghost hero" is innocent. People still remember you. No wonder Li Qingzhao wants to say "I miss Xiang Yu so far". 5. Li Qingzhao has a poem saying: "Be a hero when you are born, and be a ghost hero when you die. I still miss Xiang Yu and refuse to cross Jiangdong. " In the eyes of many people, Xiang Yu is a hero who is loyal to the liver and righteous. His invincible career and invincible record set off a surging wave at the turn of Qin and Han Dynasties. Once upon a time, the whole world admired it for thousands of years. It is precisely because of this that Xiang Yu has become a respected figure in all previous dynasties and is really admired by future generations. 6. "Pull out the mountains and villages, make great efforts to govern, and never die." What can we do if the pony doesn't die? What can we do if we are in danger? "Xiang Yu's pathetique has undoubtedly become the eternal farewell. If Xiang Yu doesn't stick to the narrow "righteousness", if Xiang Yu ... then, the person who is in high spirits, dressed and returned to his hometown, and sings "Song of the Wind": "The wind is flying, Jia Wei returns to his hometown, and it is safe on all sides" may not be Liu Bang. 7, pull the mountain and smother the world, when it is unfavorable, it will not die. What can I do if I don't die, but what can I do if I worry? The river is so long that there are countless ships moored. Even if the sky is clear and the sky is clear in Wan Li, there is no boat to carry yesterday's "pulling mountains and raging seas". Don't say that there is only one failure in life, even if there are a thousand failures, it will never erase the eternal grandeur of this stalwart man. Live and be a man among men; Die and become the soul in the soul. Today, people still miss Xiang Yu because he refused to live and returned to the East. This life made of steel is so great that it has no toughness, no expediency and reluctance. It's really a wonderful and beautiful way to live, either to destroy Qin in World War I or to die in World War I and stand upright! Jing Ke 1, Jing Ke is not wise, he can't know himself clearly. When he was in Wei, Yuci and Handan, people had low expectations of him. Wei didn't need him. He glared at him, while Lu Goujian glared at him. These people look down on him, but he thinks he is not an ordinary person. He drank with Gao Jianli all day and sang in the city, and there was no one there. Finally, it was really taken a fancy to by Taizi Dan and shouldered the heavy responsibility of stabbing Qin. As a result, the king of Qin did not die. Tian Guang and Fan Xian died on their own side, and his own death was not counted, which also accelerated the demise of Yan State. When Taizi Dan began to say that he could stab Qin, Jing Ke also said, "I'm afraid it's not enough.". Unexpectedly, due to the "firm invitation" of the prince, Jing Ke took the job regardless of this "national event". As the saying goes, "No Jin Gangzuan, no porcelain work." He Jing Ke was confused by other people's expectations. As a result, after his death, Lu Goujian laughed at him and said, "It's a pity that he doesn't talk about stabbing swords! "I scold my bag, and he thinks I have no humanity." 2. Emotion seems to be a very ethereal thing, but it is always around us. Affection, friendship, love ... it is with feelings that our life is more exciting. With feelings, we become real people. I often miss the ancient times, which was an era full of personality charm. Behind those gentlemanly manners is a person's structure supported by honesty, credit and persistent beliefs. Don't those brave people who don't go to the water miss their homeland? Doesn't he know the danger and harm of going deep into the den? He walked without hesitation, so firmly, with a cavity of loyalty to the monarch and a cavity of loyalty to the oath. Don't Lin Xiangru, with Choi in his hand, know that the king of Qin is insidious and greedy? He promised to return to Zhao intact before departure! He is following a difficult road of practicing his promise, bravely defending the interests of the country and the immortal contract in his heart. People are always influenced by feelings when they do things. Emotion is a catalyst to promote people's correct cognition of things. It is with emotion that people's cognitive desire for things is stronger and they can deepen their cognition of things. Jing Ke, who sang "Today's wind blows the water cold, and a strong man will never return" by the Yishui River, realized the significance of sacrificing for his country and the value of human beings because of his feelings for Yan. In this battle against SARS without smoke, our lovely angels in white paid a precious life, and Deng Lianxian was one of them. He said that "choosing to be a doctor is choosing to pay", from which we can see his sincere feelings for the people and patients. It is this sincere feeling that prompted him to bravely fight in the front line of "anti-Africa"; In the ward, it was this sincere feeling that made him not afraid of the danger of being infected, stick to the front line to rescue and take care of the patients, and eventually died of infection. In ancient times, Jing Ke was praised for bravely stabbing Qin. Indeed, Jing Ke's courage is extraordinary. However, I always feel that Jing Ke died in a muddle. I remember that the first sentence at the beginning of Romance of the Three Kingdoms is "the great unity of the world has been long, and the great division of the world has been long". Throughout history, this sentence is a wise saying. At the end of the Warring States Period, China was divided into seven vassal states and many small countries. After years of war, people are suffering. At that time, it was the people's wish to build a strong and unified empire. It's a pity that Jing Ke doesn't know this reason. He is bent on killing the king of Qin and contributing to a group of weak countries. However, Jing Ke was only a scholar after all, and the history before the Warring States Period was not very long. It is not surprising that he doesn't understand that long-term separation must be reunited. Not counting Jing Ke's death, the king of Qin became angry from embarrassment and ordered an immediate attack on Yan. Saving Yan didn't accelerate Yan's demise. That's how Jing Ke miscalculated. Therefore, instead of saving Yan, Jing Ke accelerated the demise of Yan, which was really stupid. 5. Jing Ke stabbed the king of Qin, which is a very popular folk story in China. "All history is contemporary history". From the perspective of modern people, Jing Ke is an out-and-out professional killer, and he may even be accused of being a "terrorist". In my opinion, Yan Taizi Dan hired Jing Ke to assassinate the king of Qin, thinking that killing the king of Qin would stop Qin Jun from moving eastward. This is a naive idea that can't solve the political problems of that year. In fact, Yan soon perished, which was related to Jing Ke's failure to stab Qin. However, Jing Ke is by no means an ordinary and simple "terrorist" in our imagination, let alone an outlaw who supports others. See historical records? Biography of the Assassin seems to be difficult to define his identity: on the surface, he is indeed a killer, but unlike Nie Zheng, who is illiterate and brave, he is "good at reading and fencing", and it is not unreasonable to call him an intellectual. In the era of the separatist war, the emergence of Jing Ke was really rare. It's a pity that Jing Ke, who is eloquent, failed to achieve the goal of self-denial, and people have infinite sympathy and pity for him. 6. According to Records of the Historian, Yan Taizi Dan told Jing Ke: "Robbing the king of Qin and learning from his land against the princes is also a great good ... so kill it." In other words, at least Yan Taizi Dan wanted to capture the king of Qin alive at first and coerce him to return the occupied territory of the vassal state. If this step is successful, they may not want to hurt Ying Zheng's life. If Ying Zheng refuses, they are going to kill him. Jing Ke's stabbing Qin reflected an attempt to prevent Qin from continuing to attack other small countries. Whether it's the plan of withdrawing troops or just delaying troops, it should be Jing Ke's last effort to solve the difficulties of Yan, and also for all the vassal states. 7. Some people say that Jing Ke was unable to extricate himself just for a promise, for a road, for the loyalty set by Yan Taizi Dan, and involuntarily alienated into a dagger that stabbed Qin. It has also been said that Jing Ke embraced faith with his life in order to fulfill the creed of "a scholar dies for his bosom friend" advocated in that era, which doomed his achievements to be a tragedy of an era. In fact, in that era of great sorrow and joy, Jing Ke was like a chess piece, without the courage and right to decide whether to win or lose. At that time, Jing Ke's choice was binary, and at the same time, his choice was also difficult. No matter which era, life and life are full of paradoxes. Faced with opportunities and challenges, we often walk out of a trap, but fall into another dilemma. People are always in a certain era. When we review the limitations of another era from one era, we often ignore the limitations of our own era. We can't use the value of the Baiji era as the standard to measure the value of faith in the Jing Ke era. So Jing Ke's choice was inevitable and helpless at that time. The success of his belief has been reflected in his persistence in the process of tragic behavior. 8. There is a view that the King of Qin should be assassinated, but Jing Ke's character and behavior are not enough, and he is not a competent assassin or knight-errant. Liu Zongyuan, a literary giant in the Tang Dynasty, wrote poems accusing Jing Ke of being "stupid", which is in sharp contrast with Tao Yuanming, a poet in the Eastern Jin Dynasty, who praised Jing Ke. Just today, many people have different views on Jing Ke, and even the same person's impression of him is full of twists and turns ... Some people think that Jing Ke failed to stab the king of Qin in the face of the king of Qin who was unable to get out because his sword was drawn, and in the face of unarmed ministers. He was carried away by the arrogance of the king of Qin and was ignorant. The negative of singing with Gao Jianli all day is revealed at this moment ... Two thousand years have passed. Objectively speaking, he is not only a chivalrous man who advocates integrity, but also a cold-blooded and ruthless assassin. Careful analysis shows that there are many heroes in history who have two sides.
