In the first month of twenty-two years, Guangdong was in an emergency, and Qishan was transferred to Guangzhou. General Jiao Ying appointed an imperial envoy to supervise Zhejiang Westernization. Su Tingkui sent a letter urging Yingjie to take the opportunity to go to Guangzhou to find out his misinformation, but he still stayed in Zhejiang. In May, Wusong fell and ordered Ilib to go to Jiangsu to prepare a camera. British soldiers have entered the river, crossed the Lieshan Pass, descended to Zhenjiang and settled in Guazhou. The elder and General Yang Wei Yijing successively called for detention and caress. In July, British soldiers went to Shimonoseki in Bo Jiangning, and Ilib arrived first. The British demanded 21000,000 taels of cigarettes, commercial debts and war expenses, and five ports of Guangzhou, Fuzhou, Xiamen, Ningbo and Shanghai traded. British officials and China officials used parallel gifts to pay customs duties and release traitors. Three days later, Jane arrived and refuted it a little. British soldiers rushed to Zhang Hongqi, planted a cannon on the hill near the city and stopped it urgently. They sent Tong En, the special envoy for the deployment of Jing Wei Xian Ling, Jiangning, Lu Zeliang, Ning Shaotai Road, and Zhang Xi and Yi Yingzhou, the wives of Ilib, and made a report according to the situation. Xuanzong was very angry, and Zhang Mu, a university student, agreed on the grounds that the teachers' salary was invalid and the payment was equal. British generals Pu Dingcha, Ma Lixun and other elders joined forces at Jinghai Temple outside Yifeng Gate and signed a treaty. Six million was given first, and the rest was given in three years.
1842 (twenty-two years of Qing Daoguang), the Qing Dynasty was defeated in the first opium war with Britain. The representative of the Qing government signed the Sino-British treaty of nanking with Britain on the British flagship "Cornwally" (Gao Yi Wally) moored in Xiaguan River (called Jiangning in Japan). This is the first unequal treaty imposed on China people by modern western capitalist countries. The British occupation of Hong Kong Island destroyed China's territorial integrity and lost its independent status. Five-port trade became the center of colonial plunder and unequal exchange of China by western capitalism. The huge compensation increased the financial burden of the Qing government, and at the same time it was passed on to the working people, making their lives more difficult. After the signing of treaty of nanking, western powers took advantage of the fire to rob and forced the Qing government to sign a series of unequal treaties. Since then, China has gradually become a semi-colonial and semi-feudal society.
