From 1899 to 1945, China experienced the most brutal aggression in history, the Qing government closed its doors to the outside world, and feudalism persisted in the Chinese nation for thousands of years. Since the Opium War of 1840, China, the holy land of oriental treasures, has made the world drool. Since 1840, China has experienced two Opium Wars and one Sino-Japanese War, each of which ended in huge compensation. From then on, foreign powers invaded China economically, from the three northeastern provinces, Hongkong and Guangzhou, and even joked that "Rome was not built in a day, but Shanghai was built in a day". At that time, Christianity in China's most prosperous city, Shanghai and China, also grew to tens of millions of believers. The rental area of the city is larger than the public area, so the powers of various countries enjoy economic prosperity in China. At the junction of Lu and Ji, there was a founder named Sanduo Zhao, the Boxer Rebellion. Under the constant occupation of foreign powers, the contradictions and conflicts between the people of China and Christianity and the foreign concession powers have intensified. Finally, various circumstances aroused the anti-Christian and anti-foreign Boxer movement of the people all over the country, and Cixi also issued an imperial edict that "people's hearts are available". With the permission of the imperial court, the Boxer Rebellion went to Beijing to carry out the anti-imperialist movement. On Dashilan Road, the busiest street in Beijing, the Boxer Rebellion burned down a western drugstore. At the same time, more than 4,000 shops in the whole street were regarded as ashes because of carelessness, and various Christian and leasing representatives also sought help everywhere. At this time, the imperialist powers began their wanton aggression against China, known as Eight-Nation Alliance, when their economic aggression was blocked, and the Boxer Rebellion was betrayed by the Qing government to protect itself, and finally died heroically. . . Cixi fled to xi 'an in the west, while Li Hongzhang began a year-long negotiation and finally reached a compensation treaty of 402,000 silver. The rare treasures of China Palace were also swept away, and China was completely reduced to a semi-colonial and semi-feudal society.
