Among them, "closed door" was the chief culprit, which also caused modern China to lag behind the world. Closing the door to the outside world is not a specific word, but a phenomenon.
In the twenty-second year of Qianlong (1757), Qianlong issued a letter and ordered to stop the foreign trade of Xiamen, Ningbo and other ports except Guangzhou, which is the so-called "one-stop trade" policy. The appearance of this decree marked the Qing government's thorough implementation of the closed-door policy. ? After Qianlong ascended the throne, he basically adopted the ancestor's sea ban policy, blocking ports and leaving only a few ports for trade. But it was in the middle of18th century, and the western capitalist countries had already started the industrial revolution, which had developed from cold weapons to hot weapons, posing a great threat to China at that time.
Moreover, their overseas trade is also expanding day by day, aiming at more resources. Western businessmen, especially those headed by the British East India Company, have been eager to find opportunities to open the China market, because China's resources were indeed considerable at that time, which was what they were interested in.
At that time, more and more foreign businessmen came to China's four coastal trading ports for trade. Moreover, many ports fell into disputes with outsiders, which quickly aroused the vigilance and disgust of the Qing government. 1740, Dutch colonists massacred overseas Chinese in Java, Nanyang, creating a shocking "Red Creek Massacre". The news shocked the whole country. I was very angry when I saw many domestic commercial ships selling goods abroad during my southern tour.
Therefore, after Qianlong returned to Beijing from his southern tour in 1757, he categorically issued an imperial edict, stipulating that foreign businessmen were not allowed to have direct contacts with the government, and only the "Guangzhou Thirteen Banks" could handle all matters related to foreign businessmen, thus beginning to implement a comprehensive policy of preventing foreign countries from closing to the outside world.
As for "36 grass sticks", it is a metaphor, it has become the territory of China! It was Gan Long who warned his children that these 36 grass sticks represented the territory of China, which could not be divided, but the land of China! But later, the country began to decline until it finally perished. ?
