What kind of allusion does the sentence "The Jin soldiers saw the Yue family army and were defeated in a single battle"?

The "History of the Song Dynasty: The Biography of Yue Fei" records that he was unable to move when he encountered an enemy suddenly, so the enemy said: "It is easy to shake the mountain, but it is difficult to shake the Yue family's army."

It is easy to shake the mountains, but it is difficult to shake the Yue family's army:

Yue Fei, courtesy name Pengju, was born in Tangyin, Xiangzhou (now Tangyin, Henan). The Yue family is relatively poor, but Yue Fei has been eager to learn since childhood, is humble, and is very filial to his parents. When he grew up, he was familiar with military books and became very powerful and good at shooting. At the age of twenty, Yue Fei was drafted into the army. He is both wise and brave, and has repeatedly performed extraordinary feats in battle.

The Yue family army he led was highly disciplined and highly effective in combat. Anyone who took any grass or wood from the civilian population would be immediately executed. Even if the common people opened their doors to stay overnight, no one dared to enter. The army's slogan is: "If you freeze to death, don't demolish your house; if you starve, don't loot." During the war, the morale of the entire army was high and they were invincible. When the enemy encounters the Yue family army, they will either be defeated or surrender.

Therefore, there was a saying among the Jin soldiers at that time: "It is easy to shake the mountains, but it is difficult to shake the Yue family's army." Zhao Gou, Emperor Gaozong of the Song Dynasty, also wrote the words "Jing Zhong Yue Fei" in his own handwriting, made a flag and gave it to Yue Fei, and appointed him as the commander of the military capital of Shenwu Hou.

Yue Fei took it as his mission to serve the country with loyalty and recover the Central Plains throughout his life. In 1130 AD, Wanyan Wushu invaded Changzhou and Zhenjiang. He wanted to cross the river and return north, but Yue Fei led his troops to intercept him and won repeated battles. In the battle of Qingshui Pavilion, Jin soldiers abandoned their corpses for fifteen miles, and cooperated with Han Shizhong to achieve a great victory in Huang Tiandang's blocking battle.

After Wu Shu escaped from Huang Tiandang, he went straight to Jiankang. Yue Fei decisively set up an ambush in Niutoushan. At night, he sent more than a hundred soldiers to sneak into the Jin camp and harass them. The Jin soldiers were frightened and frightened, and killed each other. Wu Shu fled to Huaixi in a hurry, and Yue Fei recovered Jiankang. Yue Fei had repeatedly petitioned to send troops to the Northern Expedition, but there was no result because Song Gaozong, Qin Hui and others advocated peace.

In 1140 AD, the Jin Dynasty dispatched a large army and invaded in four directions. In less than a month, large areas of land in the Southern Song Dynasty fell again. At the critical moment, the imperial court sent Yue Fei to rescue. Yue Fei immediately mobilized his troops and generals, and led his army commander to drive northward, approaching the Central Plains. Soon, generals from all walks of life came home with good news, and they recovered a lot of lost ground. Wang Gui and other generals went out to fight again, while Yue Fei entered Yancheng with light cavalry. The invading Jin soldiers retreated steadily, but the Yue family army gained momentum and was unstoppable.

Wanyan Wushu was greatly panicked and summoned his subordinates, King Longhu and others, for discussion. They believed that only Yue Fei, the general of the Song Dynasty, was unstoppable and prepared to concentrate their forces for a decisive battle with Yue Fei. When the news came, the court of the Southern Song Dynasty was horrified, but Yue Fei thought that the Jin people were desperate, so he immediately challenged Wu Shu.

Wushu gathered the troops of King Longhu, King Gaitian and Han Chang and advanced to Yancheng. Yue Fei sent his son Yue Yun to lead the cavalry directly towards the Jin army. Yue Yun lived up to Yue Fei's expectations and fought with the Jin army for dozens of rounds, killing the corpses of the Jin soldiers everywhere.

Wu Shu had a powerful army. The soldiers were wearing heavy armor, and each group had three horses connected by ropes. They were called "Kaizi Horses" and were very powerful. This time, Wu Shu mobilized 15,000 cavalry and charged towards the Song army. Yue Fei sent infantrymen with swords into the horse formation and told them to chop off the horse's legs. Because there are three "Kaizi Horses" connected together, if one is cut down, the other two cannot move, and the "Kaizi Horse" loses its combat effectiveness. The Song army took the opportunity to charge, and the Jin soldiers were defeated. ?The whole army of Guaizima was destroyed.

Seeing the continuous victory, Yue Fei said to Yue Yun: The bandits have failed many times and will definitely attack Yingchang (today's east of Xuchang, Henan). You should lead troops to support as soon as possible. ?As expected, the Jin soldiers turned to attack Yingchang. Yue Yun and Wang Gui of Yingchang cooperated with each other to surround the Jin soldiers. In a battle, Wu Shu's son-in-law Xia Jinwu and deputy commander Nianhan Suosuo Jin were killed.

Yue Fei took advantage of the victory and marched into Zhuxian Town, which was only forty-five miles away from Bianliang. Wu Shu retreated to Bianliang City and was in a desperate situation. When the good news came, all the rebels active among the people raised the banner of the Yue Family Army to attack the Jin soldiers. People from all over the country also competed with carts to drive cattle to reward Yue Jiajun. Wu Shu lamented: "Since I raised troops in the north, I have never failed as miserably as today." ?

The victory of the Yue Family Army was in sight. Yue Fei boldly announced to his subordinates in Zhuxian Town: ?Everyone, let’s fight the enemy with all our strength! When we go straight to Huanglong Mansion, we can have a celebratory drink together! ?The whole army was excited. The Southern Song Dynasty fought against the Jin army and regained the lost territory, creating an unprecedented good situation.

Killed on unfounded charges:

Song Gaozong did not want Yue Fei to continue his march, so he issued twelve gold medals to recall Yue Fei, who was stationed in Zhuxian Town. At that time, Zhang Jun's army on the Huainan East Road had retreated, and Yue Fei reluctantly retreated in isolation and without support. Before retreating, Yue Fei sighed: "Ten years of hard work have been wasted in one day!" All the acquired counties will be closed down in one day.

It is difficult to revive the country! The world of heaven and earth can never be restored again! ?

In November of the eleventh year of Shaoxing (1141), the Song and Jin Dynasties signed the "Shaoxing Peace Agreement". The two countries were bounded by the Huaishui River and Dashan Pass. The Song Dynasty ceded most of Tangzhou, Dengzhou, Shangzhou, and Qinzhou that had been recovered by Yue Fei, and paid an annual tribute of 250,000 taels of silver and 250,000 pieces of silk to the Jin Kingdom.

In December, Yue Fei was killed by Qin Hui on trumped-up charges. Yue Yun and Zhang Xian were killed at the same time, leaving an eternal hatred.
