  The third chapter of the Zhuangzi is titled “The Lord of Nurturing Life” (Yang sheng zhu 養生主). In it, the expert butcher Pao Ding instructs Duke Hui of Liang. Pao Ding describes the process of mastering his skill. His method is initially analytic; he begins by studying oxen as wholes, next as parts, and finally with faculties beyond ordinary vision. This discourse is presented as an instruction to the Lord Wenhui, who ends by saying that: “Pao Ding has taught me how to nurture life” (yang sheng, Zhuangzi 3, 124, cf. Watson 2013, 20).
