2. Zhao Gao started as a eunuch, relying on the favor of Qin Ershi and Hu Hai, he pushed the tyrannical sexual politics of the Qin Dynasty to the peak, thus accelerating its demise. Therefore, Lu Jia sighed that "Qin Ren's criminal law remained unchanged, and Zhao's death was destroyed" (referring to the demise of the Qin Dynasty); Liu Xiang, the editor of the Warring States Policy, is even more outspoken: "Qin Xin's surname is Wang, and when it declines, it is not easy to share the surname, but he dies and the country dies." Therefore, the rule of the king in the world lies in the law, not in the belief in the same surname. "
3. In addition, Zhao Gao was also a great calligrapher in the Qin and Han Dynasties. Xu Shen's Preface to Explaining Characters in the Eastern Han Dynasty said: "Zhao Gao wrote a calendar chapter, which was based on the big seal script of Shi Shua, or it was quite saved." There are 59 calligraphers in Qin, Han and Wu Dynasties in Wang Qing's Annals of Ancient and Modern Characters, including Zhao Gao. Yang Xin in the Southern Song Dynasty called Zhao Gao "a good seal character" in "Picking Names from Ancient Books". Tang Zhang Huaiguan's Shuduan, the volume of Dazhuan, said, "Zhao Gao is good at seal cutting. Teach the first emperor's youngest son, Hu Hai. " He is the author of six chapters.
