4. What is the complete poem of "Moonlight on the West Tower, eyebrows clear of sorrow"

"Happy Meeting·Speechless Alone on the West Tower"

Era: Tang Author: Li Yu

Silently, I went up to the west building alone, the moon was like a hook. The lonely Wutong deep courtyard locks Qingqiu.

Continuous cutting and confusion are the symptoms of divorce. Don't just have the ordinary taste in your heart.

1. Notes on words and sentences

① Locking the Qingqiu: Deeply enveloped by the autumn colors. Qingqiu, late autumn.

②Cut and make a jian.

③Li Chou: refers to the sorrow of leaving the country.

④Don’t mean general: There is another meaning. It's different, it's unique. [1][2] [3]

2. Vernacular Translation

Silent and lonely, I slowly climbed up the empty west building alone.

Looking up at the sky, there is only the cold moon that is as curved as a hook.

Looking down, I saw the sycamore tree alone in the courtyard, and the deep courtyard was shrouded in the cold and desolate autumn colors.

What makes people feel confused and confused is the pain of country subjugation.

The lingering sorrow lingers in my heart, but it is another kind of indescribable pain. [2]

Li Yu lived a prisoner's life enduring humiliation and humiliation. Li Yu's poems are divided into two phases based on being captured. The later poems mostly express the pain of losing the country and the thoughts of leaving the country, which are melancholy, sad, and deeply touching. "Happy Meeting" is a very representative piece of later poetry. [1]

5. What are the ancient poems about "nobility" and "indifferent"

1. Without indifference, there is no clear ambition, and without tranquility, there is no far-reaching goal. ——"The Book of Commandments"

2. The pedicle has the fragrance of gold and is indifferent, but the branches are not full and the leaves are green and peeling. ——"Remnant Chrysanthemum"

3. If you are dejected and indifferent, who can be brave and heroic? ——"Send Shen Liushi"

4. For a long time, he was indifferent, but he was full of beauty. ——"Xian Zhai"

5. Fang Yuan is frustrated and indulges in his wife, and is indifferent to guarding the farmhouse. ——"Autumn Jiao Zu"

1. Book of Commandments by Zhuge Liang

A husband and a gentleman should practice quietness to cultivate their moral character and frugality to cultivate their virtues. Without indifference, there is no clear ambition; without tranquility, there is no far-reaching goal. The husband must be quiet to study, and the talent must study. Without learning, there is no way to expand talents; without ambition, there is no way to achieve learning. If you are arrogant and slow, you will not be able to stimulate your essence, and if you are dangerous and impetuous, you will not be able to cultivate your nature. Years go with the times, thoughts go with the sun, and they become withered and withered. Many people do not take on the world, and they stay in the poor house with sadness. How will they be able to get back to you!

2. Canju Cao Xueqin

The dew and frost are gradually falling, and the feast has just passed the light snow.

The sword head is unique, and the scorched valley is nothing new.

Is Hu Wei chasing my generation, and writing is competing for excellence?

New poems are like jade chips, and when spoken, they clear the air.

If you retreat to cursive writing, nothing will happen.

Sorrow and injustice are all contained in the pen.

It is quite strange that the people of Futu regard themselves as a well.

Who can be brave and heroic if we are dejected and indifferent?

If you think about it carefully, it is not true. It is a coincidence and not an illusion.

To make poetry wonderful, be tirelessly empty and quiet.

Silence causes the movement of the crowd, and emptiness absorbs all the surroundings.

Read the world and walk around the world, observe the body lying in Yunling.

It is a mixture of sour and good things, but among them there is a lasting taste.

Poetry and method are not mutually exclusive, so this sentence should be updated.

4. County Zhai Wei Yingwu

The origin of the key:

When primitive people lived in caves, they sometimes pushed boulders to block the entrance of the cave for safety. What they were guarding against were not thieves but wild beasts. After the emergence of private ownership, thieves appeared, and the lock was born. As far back as 3,000 years ago, China had locks. However, the earliest locks had no mechanism and were just made in the shape of tigers and other ferocious animals. They were intended to scare away thieves, so they could only be said to be symbolic locks.

It is said that Lu Ban was the first person to install a mechanism on a lock. Judging from the situation reflected in unearthed cultural relics and written records, ancient locks relied on the elastic force of two leaf springs. This type of spring is still in use today.

Abroad, although the ancient Greeks invented an extremely reliable lock, it was difficult to popularize it in ordinary households because the key was large and had to be carried on the shoulders. Ancient Indians made another bird-shaped "mystery lock" with the keyhole hidden in the wings that can shake. The rise of modern locks was first invented by the British in the 18th century with the "welded fishing lock". The pin tumbler lock we widely use was invented by American Neilus Yale Jr. in 1860.

The key was invented later than the lock. The ancient Egyptians were the first to use keys in the world. Their

lock consisted of a wooden deadbolt inserted into a groove with a wooden bolt at the top. Once the deadbolt is inserted into the groove, the wooden deadbolt is inserted into the deadbolt hole. This makes the deadbolt so strong that it must be opened with a key.

Since the Egyptian locks could only be used on the side with the bolt, which was not conducive to flexible opening and closing, the Greeks developed a lock that could be opened from the other side. lock. The key made by the Greeks was a curved stick, similar in shape and size to a small sickle used by a farmer. However, some keys are up to 3 feet long and must be carried on the shoulders, which is quite heavy.

The Romans can be said to be the most sophisticated locksmiths in ancient times. They have a good understanding of the standards for making keys, and they already know how to cut the nails at the end of the keys into various shapes.
