If you want to be a young man, you must be done. The meaning of this sentence:

If you want to be a child, you must be a child, you were very smart when you were a child, and now you are very stupid.

Liu Yiqing of the Southern Dynasty Song Dynasty "The World Speaks New Words": "Kong Wenju was ten years old and went to Luo with his father. At that time, Li Yuanli was famous and was the captain of the school; Anyone who knows the door?

Cai, Qing name and middle cousin, is Tong. When the text was raised to the door, the official said: "I am the prince of Li Mansion."

Both pass, sit forward. Yuan Li asked, 'What is the relationship between the king and the servant?'

He said: 'In the past, Jun Zhongni and Jun Xianren Boyang had the respect of teachers, and they were servants and Jun Yishi. 'The gift and the guests are not surprised.

Taizhong doctor Chen Wei came later, and people spoke in their language. Yun said: 'It's been a lot, and it's not necessarily good.

Wen Ju said: 'If you want to be a gentleman, you must be a child.' He hesitated.

Later, he said that "when he is young, he may not be good", and he cannot conclude that he will have achievements in the future because he was smart when he was young. The guest said that he was young, and his age may not be good (he was very smart when he was a child, but he may not be good when he grows up) Kong Rong said, I want to be a young man (it seems that you must have been very smart when you were a child), so now ......When you grow up, you're really bad.

The implication: When he was a young man, he was clever and concluded that he would not do anything in the future.

Hour 了" ( xiǎo shí liǎo liǎo) Source: Southern Dynasty Liu Yiqing "Shishuo Xinyu - Speech Second" "It's been an hour, and it's not necessarily good." It is a choice of the words of Chen Yun (wěi) in the text. The ancient pronunciation of "了" should be pronounced as (líng, lì), to be clever and clever, which means to understand, to be smart.

Partial formal usage. It shows that a person cannot conclude that he will not act in the future just because he was clever in his youth, which means that he cannot only see things or people on the surface.

Allusion to the end of the Han Dynasty (Eastern Han Dynasty), there was a very erudite person in Beihai, named Kong Rong, who was the twentieth grandson of Confucius. He has been very smart since he was a child, especially good at rhetoric, and at a young age, he is already well-known in society. When he was ten years old, he went with his father to Luoyang (present-day Luoyang County, Henan).

Luoyang is the capital of the emperors of the past dynasties, because it is located in the east of Chang'an, called the eastern capital), at that time in Luoyang's Henan Taishou, is a very prestigious Li Yuanli, because of the Li family's name is very heavy, so in addition to his relatives, the rest of the people who came and went in the Taishou Mansion were famous people at that time. If it is not a celebrity visit, the gatekeeper does not report as usual. Kong Rong, who was only ten years old, boldly went to visit this Taishou.

When he arrived at the gate of the house, he said to the gatekeeper, "I am a relative of Li Taishou, let me know. After the gatekeeper reported, Li Taishou received him.

Li Yuanli asked him, "May I ask what kind of relationship do you have with me?" Kong Rong said:

In the past, my ancestor Zhongni (i.e., Confucius) and your ancestor Boyang (referring to Lao Tzu, Lao Tzu's surname is Li Ming'er, the word Boyang) was also a teacher-student relationship (Confucius once asked Lao Tzu about etiquette), then, you and I must be friends in the world! There were many guests present, and Li and his guests were amazed by Kong Rong's words. Among them, there was a middle doctor, Chen Wei, who arrived just later, and after the guests present told him Kong Rong's words, he said without thinking:

When you are young, you are very smart, but when you grow up, you may not be very talented. The clever Kong Rong immediately retorted: "I think Dr. Chen must have been very smart when he was young.

Chen Wei was stumped by a sentence to Kong Rong, and he couldn't speak for a long time (see "The World Says New Words").

Hehe, I guess you must have been very smart when you were a child

I was a genius when I was a child, and now ...

It's been a little small, and it's not necessarily good to be big (I think when you were young, you must have been very good and smart) The next sentence, no wonder you're so stupid now.

Rebuttal, it's been a few hours, and it's not necessarily good.
