1894 After China was defeated in the Sino-Japanese War, the imperialist countries divided their spheres of influence and demanded "dividing up China". At that time, China faced the danger of large-scale invasion and slaughter by imperialist countries for the first time. At that time, progressive intellectuals were worried about the future of the motherland and actively sought the truth of saving the country. However, the Qing Dynasty and decadent feudal forces were willing to be the running dogs of imperialism, but still refused to reform and clung to the paper hat of "China's heavenly kingdom". The feudal intelligentsia still pursued fame and fortune and clung to the remnants. At that time, although the "Westernization Movement" had actually failed, many people still stubbornly adhered to the idea of "taking middle school as the body and western learning as the use". Stimulated by this situation, Yan Fuyu published four political essays in Tianjin Direct in 1895, such as On the Urgency of World Change, On the Force, On Korea and On Saving the Nation. Actively introduce the West and criticize China's traditional feudalism, namely "textual research" and "Ci". 1897, Guo was founded in Tianjin to create public opinion for the political reform. 1898, he wrote a book of thousands of words to the Qing emperor, and put forward a specific plan for the reform, but did not submit it. This is the most progressive period of his thought. After the failure of the Reform Movement of 1898, thoughts gradually tended to be conservative.
