All the events of what has changed in Chinese history

It was the Opium Wars.

First, after the war, China's social nature underwent fundamental changes, from a backward, closed, but independent feudal country to a semi-colonial and semi-feudal society.

The second is the change in the direction of China's development, before the war China was a declining feudal power, the feudal system has decayed, and it is slowly developing into a capitalist society, and if there is no interference from external forces, China will eventually undergo a bourgeois revolution and become a capitalist country like the Western powers; After the Opium War, China's national capitalism could not have developed normally, and China could not have developed into a mature capitalist society, and finally chose the socialist road.

Third, the main contradiction in society has changed, the main contradiction in China before the war was the contradiction between the peasant class and the feudal landlord class, while the main contradiction after the war includes the contradiction between the peasant class and the landlord class, and the contradiction between the Chinese nation and foreign colonial invaders, that is, the main contradiction in society has become complicated.

Fourth, the revolutionary task changed, the original revolutionary task was to oppose the feudal forces of the country, but after the war, the task of opposing foreign colonial aggression was added, and the nature of the revolution changed from the traditional peasant war to the old nationalist revolution.

It was the first Opium War, which brought about a major change in the nature of our society, from a feudal society to a semi-colonial and semi-feudal society. The founding of New China was just an old people. Subjectivism to the new people. It's just a change in subjectivism.

There are very, very many events in China, which can be classified by object. There are Japanese initiations, and the first floor says that; There are those initiated by Wang's puppet regime, such as the April 12 Incident (or coup); There are national ** initiations, such as the Southern Anhui Incident. It's hard to answer if you don't know it.

The 77 Incident, the Southern Anhui Incident, the Xuanwumen Incident, the Lugou Bridge Incident...

PS: Too much.

There are also the Xuanwumen Incident, the Chenqiao Mutiny, the Tumubao Incident, the Xinyou Coup, the Wuxu Incident, the April 12 Incident, the July 15 Incident, the Mari Incident, the 918 Incident, the Xi'an Incident, the Lugouqiao Incident, the Fujian Incident, the Southern Anhui Incident and other incidents with the word "change".

There are also incidents without the word "change", such as the rebellion of the Seven Kingdoms, the usurpation of Wei by the Sima clan, the rebellion of the eight kings, the usurpation of power by Liu Yu, the replacement of the four dynasties of Song, Qi, Liang and Chen in the Southern Dynasties, the change of regimes in the Northern Dynasties, Eastern Wei and Western Wei, Northern Qi and Northern Zhou, the usurpation of power by Yang Jian, and the Battle of Jingnan.

The 918 Incident, the Lugou Bridge Incident, etc.

The 77 Incident, the Lugou Bridge Incident, and the 918 Incident only know so much.

For me personally, there is nothing that impresses me the most is the Qiqi Lugou Bridge Incident, the Japanese launched an attack on Wanping City under the pretext that the soldiers were missing, which opened the prelude to a full-scale war of aggression against China, and since then the land of China has been shrouded in the smoke of war, and countless people with lofty ideals have sacrificed their lives for this!

The level of education has generally increased, the infrastructure has become more and more perfect, etc.

There have been quite a lot of incidents in China, such as the July 7 Incident and the September 1 Incident in the War of Resistance Against Japanese Aggression.

The more famous incidents in modern China are the 77 Incident, the 918 Incident, and the Xi'an Incident.

The 77 Incident, the 918 Incident, the 218 Incident.

What happened in China, is it now or in the past?

If something happens, there should be a lot of identification, the incident in southern Anhui, everything is identification.

Battle of the Long Spoon.

Qin annihilated the Six Kingdoms. Anshi Rebellion.

Chen Qiaoyi mutinied.

Li Zicheng revolted.

The First Sino-Japanese War, the Long March.

First of all, your question is too big, in different eras, the answer is different, history always moves forward, no one can change the direction of the development of history, any event and person can only promote the development of history or block the development of history.

The Opium War, the War of Resistance Against Japan, the most typical.

You can talk about interesting little things, such as ......Suddenly I didn't expect it.

Contemporary, modern, or ancient?

There have been so many major events in the long history of China, can you say it? You have to give a specific time period!
