The population of Chang'an City reached 200,000, so a new market was formed outside the city wall.

People of all religions and 100 classes can be seen everywhere, including carriages transporting salt in Hedong and mule carriages transporting tea in Sichuan and Sichuan, with Chang'an City as their final destination.

The various schools of thought also established sects in Chang'an City and expanded the influence of their own sects.

The most powerful schools of various schools are Confucianism, Legalism, Taoism, Mohism, Yin-Yang, famous, mixed-class, farmer, family, straitor, military, medical, and other major schools.

The largest number of people is Confucianism. Each dynasty has masters of classics. These masters of classics have formed different schools. Some Confucian descendants forged Confucian classics and made arguments in the words of saints.

Cheng-Zhu Neo-Confucianism and Lu Wang Xinxue, even earlier, Dong Zhongshu made the best plan for Emperor Wu of Han, abolished all schools of thought and respected Confucianism alone, which was very different from the Confucianism in the pre-Qin period.

The Mo family disciples also bought a mansion with Chang'an City as the branch of the Mo family in Chang'an City.

As an academic group formed by the combination of "scholars" and "craftsmen", the Mohist school not only studied natural philosophy, but also natural sciences, especially ancient machinery.

Many Mohist disciples are experts in manufacturing armed forces.

If the scholars in Chang'an City support Confucianism, then the craftsmen in Chang'an City support the Mohist school.

While the leader of the Mo family in Chang'an City was giving lectures, a Mo family disciple came in and reported: "Sir, the famous master Gongsun Long asked for a meeting."

"Gongsun Long is here to make trouble again."

The leader of the Mohist branch couldn't help but have a headache.

Gongsun Long is a representative of famous scholars among the hundreds of schools of thought and a famous sophist, who specializes in trouble with Confucianism, Mohism and others.

At this time, Gongsun Long came to the door, mostly to embarrass him.

"Sir, please."

A Mo family disciple led a man in. When the man saw the leader of the Mo family, he said, "Today I want to debate with you that 'white horse is not a horse'."

...

After lifting the siege of Yubi City, Zhang Hua led a team of light cavalry back to Chang'an City to visit Mulan and others.

The Ya'er Army suffered heavy losses, and Bai'er Shi Jingsi broke out and met with Li Keyong.

Li Keyong and Li Cunxu retreated back to Jinzhou with the remaining soldiers.

When Zhang Hua secretly passed Zhuque Street in Chang'an City, he found that thousands of people gathered in front of a mansion, with traffic and roads blocked.

"Do you want to lead the troops to expel them?"

Lu Lingqi found that these idle people were blocking the way, and as long as Zhang Hua gave him an order, he would lead his troops to expel them.

"No hurry, I'm curious about what they want to do."

Zhang Hua is interested.

Lu Lingqi grabbed a scholar and mentioned it to Zhang Hua.

When the scholar saw Zhang Hua and his group of people were stern and were obviously soldiers, he replied in fear: "Several generals, this is the mansion established by the Mo family in Chang'an City, where they recruit disciples. Famous masters wanted to debate with the Mo family, so the villains came to watch."

"Mo family?"

Zhang Hua knew that Chang'an City was full of disciples of all religions and the Mohist family was one of them.

However, Zhang Hua was busy with war and internal affairs, and did not pay much attention to the three religions and other genres. Before he knew it, Chang'an City had already gathered a large number of people from various schools.

"The person who is responsible for setting up a mountain here is Mo Zi?"

When Zhang Hua thought of the characters of the Mo family, his first reaction was the famous Mozi.

The scholar replied: "It's not Mozi, but it's almost the same. Here, Mozi's first disciple, Qin Huali, was in charge of affairs. The one who came to debate with Qin Huali was Gongsun Long. The villain was a scholar from the Song Dynasty. Qin Huali, and Gongsun Long was a great master of the Warring States Period. He had heard of the great name for a long time. He heard that the two of them were debating here, so he came to see the style of famous masters in the pre-Qin period."

"Mo Zi's first disciple, and Gongsun Long..."

Zhang Hua didn't know that Mozi had a big disciple named Qin Huali.

As for the famous master Gongsun Long, the fame is far greater than that of the birds and slippers.

The theory "white horse is not a horse" proposed by Gongsun Long is a debate topic about logic and is quite famous throughout Chinese history, and Zhang Hua also knew it.

In the pre-Qin period, hundreds of schools of thought contend, and many interesting schools of thought were born. It can be said that it was the most brilliant and brilliant era of ancient Chinese thought and culture and the stars shining.

Zhang Hua didn’t hear about Qin Huali, but since he was Mo Zi’s first disciple, he must have learned a lot from Mo Zi.

"Let's go in and watch."

Since Zhang Hua encountered this incident, he became curious and led his troops into the Mo family's house.

All under the world is the king's land, and the shores of the earth are the king's land.

When the Mo family disciples saw that they were officers and soldiers from Chang'an City, they did not dare to stop them.

Mozi was the first to be a disciple of the bird, and sat opposite the famous master Gongsun Long, and a group of Mohist and famous disciples attended.

On the outside, there were scholars and good-good people from Chang'an City watching. Some people even climbed the wall to see the true appearance of Birds and Gongsun Long.

These are two famous figures in the pre-Qin era!

Gongsun Long caught a glimpse of a team of soldiers appearing, and even the military strategists intervened, making him more confident.

Gongsun Long took the lead in attacking Jin Huali: "The white horse is not a horse, right?"

"It's indeed a white horse but a horse!"

A group of Mohist disciples and onlookers were in an uproar. They had already guessed that Gongsun Long would use the debate topic of "White Horse is Not a Horse" to make things difficult for birds and slip.

Zhang Hua watched from the wall without much trouble, and watched the birds and slippers with interest, and Gongsun Long competed.

As a descendant, Zhang Hua lived in an era where logic was quite complete and could be expressed in mathematical formulas.

The sophistry of the white horse is not a horse is not a difficult problem for Zhang Hua.

However, in the Spring and Autumn Period and the Warring States Period, the white horse was undoubtedly a difficult problem in the ideological world at that time, causing a lot of sensation. Confucianism, Mohism, Yin and Yang schools all debated the white horse was not a horse with Gongsun Long.

Gongsun Long often makes things difficult for all schools of thought by the debate on the white horse not the horse.

If you are not careful, the various schools of thought will fall into the logical trap of Gongsun Long.

Qin Huali replied: "No, white horses are also horses."

Gongsun Long said: "Wrong, a white horse is not a horse. A white horse has two characteristics: one is white and the other has the appearance of a horse. But a horse has only one characteristic, that is, the appearance of a horse. How can a white horse with two characteristics be a horse with only one characteristic? So a white horse is not a horse at all."

Here comes!

Everyone present heard Gongsun Long's words and looked at Qin Huali at the same time.

This is a common method used by Gongsun Long during the debate and began to confuse the concept.

Bird Shakes his head: "If you have the appearance of a horse, you can say it is a horse. A white horse has two characteristics, but as long as one of the characteristics meets the definition of a horse, it is a horse."

"Similarly, white horses meet the characteristics of white. You can also say that white horses are white, but you can't say that white horses are not white."

"A white horse is a horse, so riding a white horse can be said to be a horse. A yellow horse is also a horse, so riding a yellow horse can also be said to be a horse."

"Therefore, a white horse belongs to a horse, but a horse is not exactly a white horse."

"If according to the logic of a white horse not a horse, the Chu people are not human, the beauty is not human, the man is not human, and the woman is not human, then what is the meaning of the definition of a human?"

"I don't know if you want to continue the debate?"

...

"good!"

The Mo family disciple carefully considered Qin Huali's answer to Gongsun Long, and couldn't help but applaud.

Gongsun Long shook and threw out the second debate topic: "A hard white stone, you can't see whether it is hard with your eyes, you can only see that it is white. You can't feel that it is white with your hands, you can only feel that it is hard, so there are only white stones and hard stones in the world, and there are no hard white stones, right?"

A bystander whispered, and he had already guessed the origin of the second debate topic proposed by Gongsun Long: "This is the famous 'Li Jianbai'. It's hard to deal with this."

Qin Huali fell into deep thoughts. He had to sort out the logic in order to argue that Gongsun Long was defeated.

"Mr. Li Jianbai's theory has some truth. There is a certain degree of independence between the various attributes of the same thing. Strong and white are two different attributes. People need different senses to feel it."

While Qin Huali was debating with Gongsun Long, a young man dressed in a military general appeared and interrupted the debate between the two.

Qin Huali, Gongsun Long looked at the young man who appeared at the same time, showing a look of surprise.

As soon as Zhang Hua came out, he immediately pointed out Gongsun Long's logic.

"But the biggest flaw of this theory is that it completely separates the connection between various attributes and separates the two attributes of firm and white from the stone itself. Have you ever thought that if I touch the stone and feel the hardness while looking at the stone and feeling the whiteness while feeling it. How do I say it?"

Zhang Hua's words left Gongsun Long speechless.

Zhang Hua knew that the logical basis of Gongsun Long's sophistry was to separate the connection between things. For example, the white horse was not a horse. Gongsun Long separated the white horse and discussed it one by one, so he came to the conclusion that the white horse was not a horse.

The same is true for Gongsun Long's Li Jianbai theory.

"It's amazing."

Qin Huali nodded and cast an admiring look at Zhang Hua.

“…”

Gongsun Long kept silent.

All his arguments, as Zhang Hua said, are based on the separation of various attributes of things.

If Zhang Hua pointed out this point, the theories established by Gongsun Long would collapse and he would not be able to continue the debate.
To be continued...
