Tan Sitong devoted his whole life to the reform and political reform, arguing that the only way for China to be strong is to develop national industry and commerce and learn from the political system of the western bourgeoisie. Publicly put forward the ideas of abolishing the imperial examination, developing schools, opening mineral deposits, repairing railways, running factories, changing the official system, etc., and was the most radical among the reformists. In his early years, he held the New Deal in Hunan, and used the current affairs school to train a large number of reformers. Later, he took part in and led the Reform Movement of 1898 (the 24th year of Guangxu), during which he helped Emperor Guangxu to carry out the reform, rectify the official system, and get rid of bad politics. Finally, he died for the reform with the determination of "willing to smear politics with blood", spreading new bourgeois culture and ideas and criticizing old feudal culture and ideas. Although the bourgeoisie's fraternity, equality and freedom are false, he used fraternity, equality and freedom to smash feudal absolutism and feudal ethics. Under the historical situation of old China, it has its outstanding progress in the fierce anti-feudal absolutism.
