At the beginning of the war, China soldiers and civilians rose up and dealt a heavy blow to the British invaders. However, the decadent feudal system could not resist the British invasion, and the war ended in China's failure and reparations. China's first unequal treaty, treaty of nanking, was signed. China began to cede territory, pay reparations and negotiate tariffs to foreign countries, which seriously endangered China's sovereignty. The Opium War made China a semi-colonial and semi-feudal society, lost its independent status and promoted the disintegration of the natural economy. At the same time, it also opened a new chapter in the history of modern China people's resistance to foreign aggression.
