Qianlv is one of the three commandments written by Liu Zongyuan. The Three Commandments contains three fables: the elk in Linjiang, the donkey in Guizhou and the mouse in Yongmou. This article is the second one, which tells the story of a donkey being eaten by a tiger. This article is profound in meaning, targeted and realistic. In the preface to the Three Commandments, the author said: "I am a vicious person. I don't know how to push myself and others, but I take advantage of it to show off, or I take advantage of the situation and get angry when I steal pleasure." However, death is a disaster. It is harmful to elk, donkeys and mice, as if they are things, and they commit three commandments. "It can be seen that the author wrote these three fables to warn the world: if you don't express your ambitions unconsciously, it will inevitably lead to disaster. However, Mi, Qian's donkey and Yong's mouse wrote three expressions of "putting on a show without knowing how to push others": "talking about things, getting angry with others" and "using violence when stealing". So, specifically, this article aims to satirize those who are incompetent and arrogant; Connecting with the author's political experience, we can see that this article satirizes some upper-class people in the ruling group at that time, who were arrogant, bullying and afraid of hard work, lacking talent and virtue, and being strong outside and weak inside. In addition, "three precepts" is the general title of the three articles. Taking Donkey of Guizhou as the title of this article also shows the direction of the author's ironic intention. But we can also understand the moral of this article from a negative perspective, not from the perspective that the donkey is eaten by the tiger: seemingly powerful things are not terrible, as long as we dare to fight and are good at fighting, we will certainly win the battle.
