'Uncle, what's wrong with you?' Li Chen was in a daze, remembering what he regretted last night, until he was awakened, he didn't think that now the children are asking questions.

'On this issue, Uncle wants to tell you that knowledge is to take it out and use it, and if you hide it, it is no different from nothing, and Uncle will tell you a joke today. ’

And a rich man said to a beggar, I have a great fortune, and you must respect me. The beggar replied, 'You have a lot of money, what does it have to do with me?' Why should I respect you. Then the rich man said, 'Then I will give you five thousand, and you should respect me.' ''Divide me five thousand, and I will be as rich as you, so why should I respect you?'' ’

Finally, the rich man was anxious, and he said, 'Then I will give you all the wealth, and you should respect me.' The beggar laughed, 'Then you should respect me.' ’

That is to say, you have hidden knowledge as if you did not have it. Li Chen concluded, "Therefore, any knowledge must be put to good use." ’

'It's strange, if you have less money to respect more money, then why didn't the beggar respect the rich in the first place?' ''You are stupid, it's not that the rich man has anything to do with the beggar, the beggar doesn't respect him.'' Then when the beggar became rich, why did the rich man respect him? ''This.'' The boy couldn't answer, so he turned to chess and asked for help, and what was supposed to be a question and answer between two people turned into two groups arguing.

Li Chen felt that he was off topic, a group of children are usually very lively, Li Chen also likes children to ask questions, likes them to think arbitrarily, and the consequence is that it is super easy to go off-topic. Before a problem is solved, they can create a new problem.

Fortunately, this group of children argued and argued, one did not evolve into a quarrel, and the other was that after arguing for a while without result, they quieted down, Li Chen continued.

You have just said a lot, why does the beggar not respect the rich man, and when the rich man gives all the money to the beggar, he asks the beggar to respect him. ’

The beggar disrespects the rich man because it has nothing to do with him. If the rich man had paid a month to the beggars he had always employed, the beggars would probably have respected him. ’

'Huh? Why give every month to be consistent, will be respected. It's not okay to give 5,000? Because, Shengmien, Doumien. The beggar just doesn't respect the vice-rich. ’

'Give it every month, and the beggar will look forward to getting it again next month, or even twice. Directly get 5,000 yuan, it's a person, I'm afraid I will think about it, I want more. has always been within the beggar's bearable range, 5,000 guan, he may kill the rich man, and the remaining 5,000 guan will appear. ’

'Off topic..., well, what Uncle wants to tell you is that knowledge must be taken out and used, otherwise it is almost the same as nothing. Li Chen explained again, and then remembered that today is not a class, it is an extracurricular activity, and I really want to continue to play, and I will talk about it in class.

As for the question of whether our knowledge will be learned by others. First of all, you can find a way to package it, move and fix the principle of the pulley, you know, but outsiders don't know, a little cover up, outsiders can't understand it, they will only feel amazing. ’

Furthermore, this is a simple principle that will be seen through at once, but what if it is a more complex way? Li Chen continued, "The complicated method will not be seen through at a glance. ’

The crane is just a simple thing, you can see through it at a glance, and you can imitate it if you don't understand it. However, many things need to be studied and understood in depth before they can be created, and those things have to be studied in the front before they can be fruited later. ’

When the time comes, don't say that you can understand it at a glance, and even if you teach him specifically, he may not be able to use it. In fact, the most important thing is to need a patent law, but the Tang Dynasty wants to have a patent law? This kind of thing will be a thousand years later, and the Chinese will not understand it.

However, Li Chen is not wrong about one thing, modern products are no longer imitations at a glance. You have to have a deep industrial foundation, without that condition, people are willing to teach by hand, and you don't want to copy it. You don't even know the way, it's hard for you to even use it. Why does Apple sell so well, isn't it because it's so simple? In modern society, even simplicity is a science.

Li Chen handed over the children to a few craftsmen, the craftsmen were very reluctant, a group of hairy children, if they had their own children, then they could naturally, the craftsmen were hereditary, and their children were also taken with them since they were young, teaching skills by hand.

But other people's children are still the owner, and it is awkward to take them around. Many people are complaining in their hearts, what is this for, are they worried about their own craftsmanship?

Later, they changed their minds, and the crane was not so easy to set up. Maomao used some simple tools and built a simple crane to make it easier and faster for them to carry heavy objects. This made those craftsmen very surprised, how can it be so easy to carry heavy loads?

Children can write and calculate without taking a crane, and help the craftsmen to deal with a lot of things, making it a lot more convenient for them. Don't look at them as senior technicians, in fact, they can write, but there are really not many. A lot of things are based on experience.

The children went to help, Li Chen got a basin of cold water, washed his face, and had a terrible headache. He remembered again that he sang that laughing Hongchen last night, and was ridiculed by Luo Yin, and it was still a problem like that, the song was good and the lyrics were too vulgar.

He drank a few glasses higher. began to use chopsticks to knock on plates and bowls to give himself rhythm, and began to sing and laugh Hongchen. This is a song that Li Chen likes very much, Lin Qingxia plays the undefeated Dongfang, puts on women's clothes, goes to a simple prostitute den, and plays this song when she picks up the pipa.

It's simple to remember the lyrics, Li Chen sang a piece, Luo Yin would sing it, and then Zhao Liu listened to it again, and then asked the servant to take the instrument and start accompaniment. Then Luo Yin bluntly criticized, the song is good, and the words are poor. Zhao Liuyi also bowed his head frequently.

It's okay if it's just like this, but the problem is that Luo Yin is very interested in discussing it with himself and composing music. I have to say that I am pleasing to the eye, and I can point out that I am quite talented.

It's really enough, it's all about what is harmed by dancing. If it weren't for the high dance, he wouldn't have drunk so much, he wouldn't have drunk so much, he would have been vigilant at all times, and he wouldn't have sung that laughing Hongchen. Or that it won't be sung in front of outsiders.

It's all because he didn't inquire clearly, although he knew that Tang people loved to dance, and he was a little prepared. But I didn't expect that there would be a forced invitation to dance. After all, this custom has been lost for thousands of years to future generations. Modern people should really review, the ancients were much more open than modern people.

Or to be correct, the Han and Tang dynasties, was it really a relatively open dynasty? (To be continued.) )
