In later generations of India, Bangladesh, Sri Lanka and other countries widespread in India, Bangladesh, Sri Lanka and other countries based on the theory of descent of a social system, of which India is the most serious, also known as the lowly system.

The caste system in India is derived from Hinduism, also known as the Varna system, which was formed in the late Vedic era and has a history of more than 3,000 years. This system divides people into five classes, namely Brahmins, Kshatriyas, Vaishyas and Shudras, and Untouchables.

According to the Varna hierarchy depicted in the Rig Veda: Brahmins are the mouths of the primordials, Kshatriyas are the arms of the primordials, Vaishyas are the thighs of the primordials, and Shudras are the feet of the primordials. As for the untouchables, they were excluded from the bodies of the original people.

This caste system is the most typical and strict hierarchy in the ancient world, and the various hierarchies under the caste system have been passed down from generation to generation, even in the twenty-first century when Li Nan's soul has traveled, the system still exists.

In the early days of the establishment of Zhennan, Li Nan eliminated the slave-owning class and liberated a large number of oppressed slaves because of the attack on Jiaozhi and Zhancheng, which was also the foundation of the empire at that time.

Originally, Li Nan thought that slavery and caste hierarchy would never appear in the country he had established, but it turned out that when he was busy taking risks and fighting the Jin Kingdom, these two despicable systems in human history actually appeared quietly in the empire, and they were becoming more and more violent.

Thanks to the strength of the Chinese Empire, this invincible and increasingly prosperous country exudes a formidable appeal.

It was a good thing that people from the surrounding regions and small countries flocked to the empire, but when there was too much foreign population, the survival of these foreigners did have a big problem.

After these foreigners came to this country, many of them chose to work for others or even sell themselves into slavery in order to survive.

It can be said that being a slave in the rich landlords of the empire is far better than their original living environment, so more aliens have chosen this way of life.

In addition, those foreign prisoners of war who were released from labor camps due to their maturity also faced the dilemma of survival, which led to the increasing number of slaves in the empire, although the empire was different from ancient Rome, and the current slavery system was milder.

In order to completely solve the problem of slaves, we must not only arrange the means and environment for them to survive, but also face a more serious problem, that is, the complete abolition of human trafficking.

In later times, any human trafficking was a crime, but in this day and age, it was a common occurrence.

In the history of China, almost all dynasties allowed the buying and selling of human beings. Even in the Qing Dynasty, even if there was already a germ of human rights awareness, human trafficking was still commonplace.

There are many descriptions of maid buying and selling in "Dream of Red Mansions", Xue Pan and Feng Yuan competed to buy maids, coveted the beauty of maids, and wanted to accept concubines, and the maids who were bought and sold did not even have the freedom to be the masters.

Buying and selling human beings was tacitly permissible in feudal society, but buying and selling human beings was different from abduction, so all dynasties and dynasties had relevant regulations on human trafficking transactions.

For example, as stated in the "Tang Law Discussion", in addition to selling and selling (i.e., being sold voluntarily), snatching or deceiving a person is a crime and should be punished in accordance with the law. If the person being sold is under the age of 10, even if it is voluntarily sold, it will be determined as robbery or deception.

Moreover, in various dynasties, there was not only a set of procedures related to human trafficking, but also special places for sales, and Li Nan also bought a large number of homeless people in Tokyo City as his team.

When the Chinese Empire was first founded, it was far from the customs and laws of the past, and it was not fully integrated with later generations, such as gambling, green houses, and human trafficking.

Gambling and the Qinglou industry are connected to the instinctive desires of human beings, not to mention this era, even after many years, whether it is a developed or underdeveloped country, there is no possibility that it can be completely banned.

And it is difficult to completely prohibit human trafficking for the time being, because most of the wealthy Han families in the empire have more or less slaves, and once the relevant laws are enforced and enforced, it is very likely to cause the foundation of the country to be shaken, not to mention that there are Jin and Western Xia in the surrounding area.

In addition to the big problem of slaves, Li Nan was also worried about the caste system.

According to the investigations carried out by Dorcott and Varys, among others, there are now several classes within the empire.

First of all, the first class is the people of Lingnan and the Indochina Peninsula and the Han people in the area south of the Yangtze River.

The people who originally belonged to the Guangnan West Road, Jiaozhi, Zhancheng and Dali areas in the Song Realm belonged to the first inhabitants of the empire, and the soldiers and generals of the major group armies of the empire all came from these places at the beginning, so they had the superiority that I was the people of the empire.

The people at the same level as these people are the people of the Song Realm south of the Yangtze River who were captured by the empire very early, and most of them are Han people, who have the same ancestors as the emperor, and they have been fully supporting Li Nan and the empire during the period when the country expanded outward and became stronger.

The second class is the Han people north of the Yangtze River and south of the Yellow River, who joined the empire a little later, and many of the displaced people have been relocated to other regions, so they are discriminated against by the first class, but it is not very serious.

The third estate is the common people of all the regions north of the Yellow River that the new invasion of the empire has occupied, and these people are now just beginning to integrate into the empire, and the imperial people south of the Yellow River call them the northern barbarians.

The fourth class is those who have been reformed into labor camps and regained their freedom.

They started out as soldiers of the Empire, and after three to five years of labor reform in labor camps, they received an imperial pardon and became subjects of their own country.

Just like criminals who have been in prison, even if they change their ways, there will still be people who look at them with colored eyes after they come out, so their social status is not high.

The last group is the migrants and fugitives from all countries.

The Jin Kingdom, the former Liao Kingdom, the Island Kingdom, the Western Xia, Goryeo, the Zhenla Empire, and the Tibetan people all belonged to this category, and in the minds of the people of the empire, even if they lived in the empire, they were still foreigners.

The Chinese people are indeed inclusive, but as the masters of the Central Plains and the creators of countless great civilizations, their own arrogance and discrimination against these foreigners are also from the heart, and it is difficult for people to think that many years later, there will be Han people who worship foreigners and flatter foreigners.

These two problems were placed in front of Li Nan, the emperor, and even if he had many sources to learn from, there was no good way to solve them for the time being, so he had to summon Tyrion and all the interior ministers to discuss the matter.
