Tan Sitong's representative work is "Renxue", and later generations compiled his works into "The Complete Works of Tan Sitong". I looked at the door and stopped thinking about Zhang Jian, and waited for Du Gen for a moment. I am smiling towards the sky with my horizontal sword, leaving my liver and gallbladder intact. This is a desperate poem written by Tan Sitong on the prison wall before he was executed. It is said that this poem was "tampered" by Liang Qichao. The original poem is: "Looking at the door and throwing toes to pity Zhang Jian, directly admonishing Chen Shu for being ashamed of Du Gen. Throwing a European knife in hand and looking up to the sky, smiling, leaving the general guilty for future generations to judge." There is insufficient evidence. Hard to believe.
