Tan Sitong (1865-1898), a native of Liuyang, Hunan, was a famous bourgeois politician, thinker and reformer in modern China. He argued that China could only be strong by developing national industry and commerce and learning from the political system of the western bourgeoisie. Publicly put forward the idea of abolishing the imperial examination, developing schools, opening mineral deposits, building railways, running factories and changing the official system. Write an article attacking the Qing government's policy of traitorous surrender. 1898 was killed after the political reform failed. He is only 33 years old and is known as one of the "Six Gentlemen of the 1898 Movement".

Liang Qichao evaluated Tan Sitong as a "comet in the ideological circle of the late Qing Dynasty". Its eternal famous sentence "I laugh at the sky from the horizontal knife to leave two Kunlun mountains!" " "This is Tan Sitong's swan song before he was executed in Ge Tan. It means that I was born for political reform and died for political reform. A life and death, loyalty to the liver and righteousness. Ge Qinsheng is like Kunlun and dies like Kunlun. " Tan is in prison, self-righteous, wandering around the room all day, picking up the coal ash on the ground and whitewashing the account books. What do you ask? Laugh and say: make a poem. "
