The closed-door policy during the Qianlong period left China far behind the West.

In the modern history of China, the influence and harm of closed doors are well known. It can be said that the implementation of the closed-door policy has changed the historical trend and made China, which has always been strong, stagnate and lag behind. Incredibly, this policy was formulated in the prosperous time of Kanggan. Which emperor closed the country? It was Qianlong who promulgated and strictly implemented the closed-door policy. In fact, as early as the Kangxi period, some policies that explicitly stipulated to be closed to the outside world were already being implemented.

The young Kangxi ascended the throne at the age of 8, became a leader at the age of 14, and died at the age of 69, reigning for 6 1 year. At that time, young Kangxi faced the imperial court under Ao Bai's dictatorship, the separatist regime in Taiwan Province and the Junggar rebellion outside the imperial court, and Russian overseas aggression. Kangxi killed Ao Bai, recovered Taiwan Province province, put down three rebellions and Junggar rebellion, and stopped Russian invasion. Now Russia has basically established the territory of China and is a defender of multi-ethnic unity. However, at that time, in order to prevent pirates from escaping, foreign invasion and anti-Qing uprising, some measures to restrict trade were promulgated. During the Qianlong period, trade became more frequent and anti-Qing uprisings continued. In order to maintain the unity of the Qing government and prevent the success of the anti-Qing movement, Emperor Qianlong believed that China was vast in territory and abundant in natural resources, which was sufficient for self-sufficiency. In 757, the closed door policy was officially promulgated, which was very convenient. Until 1840, British guns smashed the country's closed-door policy.

To find out which emperor closed the door, we must distinguish the essence of the problem. Under the impetus of Kangxi and Yong Zhengdi, Emperor Qianlong officially promulgated and strictly implemented the closed-door policy. The closed-door policy of the Qing Dynasty gradually isolated China from the world, and eventually completely lagged behind the western countries. This issue was also considered when the Qing dynasty closed its doors to the outside world, and some ministers of North Korea also agreed to this motion. The Qing dynasty closed its doors to the outside world for a purpose.

One of the purposes of closing the country to the outside world is to prevent the domestic anti-Qing forces from combining with the anti-Qing forces in Nanyang. The rulers of the Qing dynasty were all foreigners, and the land annexation was serious in the later period. In the lower classes of the Qing Dynasty, many desperate peasants chose to rebel. However, China immigrants from all parts of Nanyang were from the Ming Dynasty, so they always had the responsibility to overthrow and restore the Qing Dynasty. The second purpose of the closed-door policy is to prevent the invasion of Japanese invaders and European colonists. During the Ming Dynasty, Japanese invaders invaded the southeast coast of China, and the closed door policy could prevent some domestic profiteers from collaborating with the enemy. During the Qing Dynasty, western colonists gradually invaded Southeast Asia, and the implementation of the closed-door policy also took into account the prevention of these western colonists. The fundamental purpose of the Qing dynasty's closed door was to maintain feudal rule. The Qing Dynasty was a dynasty established by Jurchen, and the ruling class was mainly Manchu. The lower Han people were oppressed by the government for a long time and rebelled against the Qing Dynasty. Nanyang immigrants came from the late Ming Dynasty. They don't like the Qing Dynasty. The closed-door policy of the Qing Dynasty prevented these people from contacting China. The Qing court was also worried that the western colonists would support the Han people to oppose the Qing Dynasty, thus preventing westerners from entering China. Although the implementation of the closed-door policy was unfavorable to China, it maintained the feudal rule of the Qing Dynasty to a certain extent.

Closing the country to the outside world is a closed national policy, which strictly limits the economic and cultural exchanges between China and other countries. The main manifestation of the closed-door policy is that the state implements a strict policy of prohibiting the sea, ordering coastal residents to move inland for dozens of miles, and stipulating that they are not allowed to go to sea without approval. This policy has affected many people living in coastal areas and changed their living environment and living conditions. At the same time, the state also prohibits merchant ships from conducting maritime trade and stipulates that it is forbidden to establish trade relations with foreign countries, which seriously hinders exchanges between countries. In fact, this country hopes to limit the communication between the people and the outside world and reduce the problems caused by domestic turmoil. In addition, the reduction of foreign trade ports from four to only one has also restricted the national economy and trade. In addition, the reduction of trading ports has greatly closed people's lives and had a far-reaching adverse impact on the country's subsequent development. In addition, the state strictly restricts the types of imported goods. This restriction inhibits the development of national commerce and trade, and also seriously affects the country's foreign exchange and development. At the same time, restrictions on the types of imported goods are not conducive to cooperation and development between countries, and also hinder cultural exchanges. Judging from these performances, the closed-door policy restricts the development of foreign trade and commerce, and to some extent, inhibits the economic development of China. At the same time, it also exposed the conceit of the ruling class, as well as its blind arrogance, stubborn xenophobia and lack of ambition. However, these measures seriously hindered the communication between China and the outside world in many aspects, and prevented foreign technology and culture from being introduced into China in time.

The closed-door policy of the Qing Dynasty brought a profound crisis to China, which made the whole China gradually lag behind the West and was finally humiliated by the western colonists. The historical lessons of closed doors remain in people's hearts, inspiring people to work hard for the rejuvenation of the Chinese nation. The closed-door policy of the Qing Dynasty cut off the contact between domestic anti-Qing forces and foreign anti-Qing forces, but consolidated the rule of the Qing Dynasty to some extent. However, in the late Qing Dynasty, western colonialists invaded China one after another, and China suffered repeated wars and defeats, and signed many unequal treaties. Closing the country to the outside world brought humiliating historical lessons to the country, and the Qing Dynasty successively signed unequal treaties with many countries. The treaty with Britain ceded Hongkong, the treaty with Japan ceded Taiwan Province Province, and the treaty with Russia ceded the three northern regions. There are many historical lessons from closing the door to the outside world. For example, if you don't communicate with the world, you will be abandoned by the world. Before the Ming Dynasty, the Tang, Song and Yuan dynasties interacted with the world, which had a great influence on the world. In the Qing dynasty, the Qing court closed its doors to the outside world. By the end of Qing Dynasty, China was far behind the western countries in many aspects.

At that time, the weapons of western countries were muskets and cannons, while those of China were cold weapons. It is natural for cold weapons to fail when dealing with rifles and artillery. Western countries carried out industrial revolution, and some production was carried out by machines. But in China, production is workshop production, purely by hand. In every respect, China has been surpassed by western countries. In the eyes of westerners at that time, China was the most backward and ignorant country.
