The Qing dynasty closed its doors to the outside world and was scolded by later generations. When did the Qing dynasty begin to close its doors to the outside world?

1723 (the first year of Yongzheng), due to a fierce dispute with the Holy See about Chinese etiquette, Yong Zhengdi banned Catholicism, banned foreign missionaries from preaching in China, and restricted trade, which was regarded as the beginning of the national lock-up.

By 1757 (twenty-two years of Qianlong), Emperor Qianlong had issued an imperial edict from Beijing to coastal provinces, ordering Xiamen, Ningbo and other ports to stop trade with the West, which was the so-called "one-stop" policy.

Its positive influence is to crack down and limit rampant maritime smuggling and piracy to a certain extent. It has played a positive role in the stability of coastal areas. It played a certain role in self-defense against the aggression of western colonialists.

The negative impact is the long-term implementation of this policy, which has hindered the contact between China and foreign countries, affected China's absorption of advanced culture and science and technology, isolated China from the world, and seriously hindered the budding development of capitalism. It derailed China and the world, and slowly fell behind the world.
