As for the problem that civilization thrives when it is open to the outside world and declines when it is closed to the outside world, it is enough to explain it with historical materials, and the number of words cannot be too small. The four most powerful dynasties in history, the powerful Han Dynasty, the prosperous Tang Dynasty, the wealthy Song Dynasty and the Ming Dynasty, did not close their doors to the outside world (the Ming Dynasty imposed a maritime ban, not to cut off contact with the outside world like the Qing Dynasty, but to restrict non-governmental trade and prevent the Japanese pirates and the Buddha Langji people from entering the Ming Dynasty. Foreign trade was controlled by the state and all profits were earned by the state. During the Ming Dynasty, more than a quarter of the silver mined in the world every year was imported through trade.

Therefore, it is wrong to say that "closed doors will lead to the decline of civilization". Apart from the Qing Dynasty, China was never closed to the outside world. The decline of Chinese civilization has little to do with it. The main reason for the decline of China is that the industry and firearms in Qing Dynasty were very developed in Ming Dynasty. There were 4600 soldiers, 400 guns and 80 guns in the Magic Machine Camp of the Ming Dynasty. In the Ming Dynasty, firearms were everywhere among the people, especially some pawn shop bodyguards. By the end of the Ming Dynasty, the firearms in the Ming Dynasty were gradually inferior to those in the West. The main reason is that the dominance of the Ming Dynasty in the East was not threatened and stimulated by external factors, while the development of military science and technology in the West was slow, on the contrary, so military science and technology developed rapidly. However, the Ming navy immediately bought Portugal at a high price after the Nanyang generation lost to the Portuguese fleet. China Artillery also invited Portuguese as instructors to teach the soldiers advanced firearms knowledge. At that time, Fujian organized a group of advanced firearms troops with a large scale. However, at that time, the Ming dynasty was gradually dying, and the chaotic currency led to an endless stream of uprising troops. Finally, the insurgents led by Li Zicheng defeated the Ming army and occupied Beijing. At this time, various forces within the Ming Dynasty were divided. There was no power to resist foreigners at all, so Jin found a bargain in this harsh environment and established it after the Qing Dynasty. In order to prevent the anti-Qing dynasty from regaining sight, civilians were forbidden to manufacture firearms, which led to the fact that when Eight-Nation Alliance entered Beijing, the troops who fought back didn't even know the muskets.

Only120,000 people entered the Qing Dynasty, while hundreds of millions of people in the Ming Dynasty burned ancient books, tampered with history and slaughtered people madly in order to consolidate their rule in the Qing Dynasty. For example, after the Ten Massacre in Yangzhou and the Three Massacre in Jiading, even Han people who had no special regulations on service and appearance were required to cut their braids. Forcing the Han people to accept the idea of enslavement and close their doors in this way is just one of the many policies of the Qing Dynasty to oppress the Han people.
