The third problem is to distinguish the authenticity of the golden crown. Yun Yao has two golden crowns on his hand, and there is no difference between the naked eye. The weight is the same on the scale.

In fact, there are still differences in size, but it is difficult to detect with the naked eye.

"If you can melt the golden crown or split it, you can know whether it is pure gold inside the golden crown. The difficulty is that you cannot destroy the golden crown." Mo Zi has decided that once Yun Yao answers this answer, they will enter the Mo family.

The third question is also the most difficult. How to judge the authenticity of the Golden Crown without destroying it?

In fact, it is very simple. Just rely on different density. Volume is equal to weight divided by density. Different density and equal weight, the volume must be different.

If the volume is different, even if the naked eye cannot see it, it can be judged with water.

"There is a bucket full of water here. Put the golden crown into the water separately to see if the volume of the overflowing water is the same, you can tell whether it is true or not." Yun Yao said.

The result is that there is not as much water overflowing.

"That is, the weight is the same, but the volume is of size." Measurement of volume with water is much more reliable than eyes, especially when the volume of the golden crown is irregular.

"Although I know that the size is large, how can I know which one is true and which one is false?" asked Taoist Lingbao. If he had not lost his cultivation level, he could only know it by counting his fingers, but now he couldn't figure it out.

"I have a gold nugget of the same weight here." Yunyao sent the gold nuggets to the water and collected the overflowing water: "Now we have three parts of water here, just compare it and you will know the result."

Although Mo Zi didn't know the principle, he believed that this method could indeed determine the authenticity. After all, the water overflowed from an equal amount of pure gold should be the same. If it is different, it means it is not pure gold.

"How?" Yunyao asked Mo Zi to fulfill his promise.

"I am convinced, and from then on, you five are also disciples of the Mo family." Mo Di kept his promise.

Next, Yunyao also met several of Mozi's disciples. In addition to the Lingbao Taoist, there were also birds, high stones, plowing pillars, and following the cave.

Compared with the sons of Confucian disciples such as Zilu, Zigong and Yan Hui, the core disciples of the Mohist school are all called by names instead of ‘character’. These elegant names also indirectly reflect that they are not particular about people and have no habit of paying attention to them.

Yunyao found that some of the disciples' eyes were full of unhappiness, and knew that he would definitely conquer them with his strength in the future. The technicians would use their skills to speak.

"Come here, I have seen the giant together." Yun Yao and the four beauties salute to the giant together.

Mo Zi nodded. He now wanted to have an in-depth discussion with Yun Yao on the three major problems of Zhu Cheng and understand the deep rules of the three questions.

The conditions of the Mo family were very difficult. Although Yun Yao was not a cook this time, she did more work than a cook. Because the Mo family did it by themselves and supported themselves with their own skills, especially in the early stages of entrepreneurship, various problems followed one after another, so they made money during the day and learned their ideas at night.

Fortunately, the Mohist family is very down-to-earth, and loves both the same and meets the needs of craftsmen to be stable, so many people in Zhucheng are willing to join the Mohist family. As long as there are more people, the core Mohist people will have time to improve their opinions.

As the core of the Mohist school, the "universal love" has basically been completed. By comparing people to God's property, it is inferred that God loves everyone and does not want human race to fight.

But how to achieve unity love still needs to be added. After all, saying and doing is not the same thing as doing.

Therefore, the Mohists think that it should be "same" means to listen to the commands of the leader, and the leader should listen to the commands of the leader... In the end, everyone will listen to the commands of the king together, and the king must listen to the commands of God. God loves both, so the king must love both, and the monarch's doctors must love both. To the extent that everyone has to love both.

Because you have to listen to the orders of your superiors, and your superiors love each other, so love each other is implemented for everyone.

After listening to "Shang Tong", Yun Yao thought that the Mohist demands on the kings higher than that of Confucianism. Because Confucianism only requires the kings to be kind, benevolence comes from the heart, and whether to practice benevolence or strict can be floating. The Mohist demands on the kings to be both love, and through God's constraints, God cannot touch or see, and the king must have a certain amount of wisdom to accept both love.

Of course, in Yunyao's opinion, neither is good, but the Confucian inner saint can make specific requirements from the point of human nature. However, it is unrealistic to restrain the king through God. The Mohist school lacks experience in governing the ruler, which is too natural.

This also reflects the difference between the starting point of Confucianism and Mohism. Confucianism calls for the aristocratic spirit. This kind of thing did exist in the early Western Zhou Dynasty, so Confucians can resonate with the king and pursue the same moral benchmark. However, the Mohism was born with mud legs, and they did not have any common language with the king. They knew very well that the king would not listen to the requirements of the craftsmen at all, so they had no choice but to hope that God would restrain the king.

Jiao love is good, but it is difficult to implement.

Confucianism later upgraded to the "internal sage and external king", making up for the shortcomings of being difficult to restrain individuals by relying solely on morality. Only by cultivating morality and assisting the kingly way outside can one last for thousands of years.

The Mohist school is ahead in terms of technical capabilities, but the system of "Shangtong" can only be implemented within the Mohist school and cannot be promoted to the world.

As the number of people increases, all Mo family disciples are Mo people, and they must abide by the rules of the Mo family and obey the orders of the leaders.

There is no problem with the ink master, because as craftsmen, they can only complete huge work by following the command of the contractor. For example, every craftsman can only complete one job in building a house, so there must be a coordinator. If the coordinator has strong ability, the building of the house can be organized, and the craftsmen can only complete the work at hand with peace of mind. If the coordinator is not capable, the craftsmen will be very tired and the parts they make cannot match, and the efforts of the craftsmen will be gone.

Therefore, there are many internal rules of the Mohist school, and disobedience is not allowed.

The Mohist school, like the future peasant uprisings, had limitations. However, Yun Yao still studied the Mohist thought seriously. After all, there are still many things worth learning, such as the idea of ​​"salvation, burial, etc., which oppose extravagance and waste, and the proposal of preparing for war and famine was very consistent with the late Spring and Autumn Period.

Yunyao has no objection to the idea of ​​"love each other and benefiting each other". She focuses on technology in the Mo family and the definition of various phenomena.

Not only phenomena that can be observed in nature, but also perceptions and experiences that cannot be observed but perceived are defined from concrete to abstract.

For example, force is the reason why shape is vigorous. That is to say, force can produce deformation.

Of course, in addition to the physical definition, there is also a moral definition, such as "filial piety and benefiting relatives", as well as a good and bad qualities such as courage, integrity, and flattery, as well as a definition of life and human behavior, such as "birth, form and place of knowledge", "dream, and lie down and take it as if it is", such as "rewarding, reporting and knowing achievements".

Yun Yao thought that he had written "Er Ya" before, but unfortunately Er Ya did not promote it. Of course, Er Ya did not explain force, time, and space. The main purpose is to standardize Ya language and standardize pronunciation.
