China was a slave society from Xia, Shang and Zhou Dynasties, and a feudal society from Qin Dynasty to Qing Dynasty. The history of Tang, Song, Yuan, Ming and Qing Dynasties is also a feudal society. There are several main differences between constitutional monarchy and constitutional monarchy:

1, emperors have different powers. The ancient emperor of China was supreme and controlled the life and death of his subjects. The monarch in the constitutional monarchy is mainly a symbol of the country and has no real power.

2. Their social systems are different. China in ancient times belonged to feudal social ideology in Tang, Song, Yuan, Ming and Qing Dynasties. Constitutional monarchy mainly lies in the ideology of capitalist society.

3. The developed degree of social productive forces is different. The ancient feudal society in China was mainly a self-sufficient feudal small-scale peasant economy with backward productive forces, while the constitutional monarchy was a capitalist system with developed productive forces.

Extended data:

The Opium War was a decisive battle between British capitalist countries and feudal society in China, which led to the failure of the self-defense war and made China a semi-colonial and semi-feudal society.

During the Opium War, the Qing government successively signed a series of unequal treaties, which seriously damaged China's sovereign independence and territorial integrity, not only brought about fundamental changes in China's social, political, economic and other fields, but also caused changes in the ideology of patriots.

The degree of semi-colonial and semi-feudal socialization in China is deepening. China's patriotic soldiers and civilians are constantly fighting bravely, and China's history has also initiated unremitting exploration of social progress.
