There are no immigrants in Qin?

During the Warring States period, Qin was a vast country, occupying all or most of the five provinces of Shaanxi, Gansu, Sichuan, Chongqing, Qinghai and Ningxia. Most of these areas are underdeveloped. Compared with the six countries with narrow land and sparse population, Qin is more suitable for introducing immigrants from the six countries. However, there are almost no records in the historical materials that the people of the six countries took the initiative to go to Qin, and there are quite a few records that the people of the six countries did not want to become Qin people. Before the battle of Changping, the Shangdang County people in South Korea who could have been directly incorporated into the State of Qin forcibly ceded Shangdang to the State of Zhao. They would rather suffer from war than be Qin people, which shows their great determination not to be Qin people. Not only did the people of the six countries not want to go to Qin, but the people of Qin even fled Qin.

After the State of Qin seized a part of the land of Chu, the Chu people on these lands became Qin people. However, these new Qin people who were finally bathed in the virtues of Qin were very dissatisfied. They kept fleeing to the state of Chu. What is even more surprising is that not only these new Qin people escaped, but also some old Qin people fled to Chu together at their instigation. At that time, the Qin system was far superior to the six countries, but the superiority of the Qin system was mainly reflected in the agricultural war. The so-called agriculture means vigorously carrying out agricultural production at home, and the so-called war means wantonly carrying out merger wars abroad. During the Warring States period, it was impossible to use science and technology to achieve a leap in national strength as it is today. The essence of Qin system is to strengthen the control and oppression of the people, so that as much people's power as possible can be used by the state.

The reason why Qin can unify the whole country is mainly because its level of organizing and mobilizing people's power is much higher than that of the six countries. Naturally, the people of Qin also have to bear more tax burden, labor and military service than the six countries. The six countries can also dawdle, fishing for three days and drying their nets for two days; Not in the state of Qin, 365 days a year, the government has arranged for you to be full, and you can't stop for a day. In the six countries, you can still depend on the nobles, pay less taxes and save more food; Not in the state of Qin, except the living rations, all the others belong to the king of Qin, and they have to be transported to the front to serve as rations. The six countries can occasionally become extra-legal people and evade military service, but the government is not sure anyway; Not in the state of Qin, the census thieves are diligent, and there is a system of "Jiabao Left Alliance", with ten households and one family and one treasure. If you dare to evade military service, let alone the government, the villagers will break your legs first.
