〈Mountain wood〉 the 20(superscript th), a follow-up of 〈Human world〉the 4(superscript th), is an important chapter in 〈Zhuangzi〉 on how to deal with the world. Life philosophy depicted in the chapter can be categorized into humbling oneself and complying with the nature. These two self-cultivation skills can be seen as part of the connotation of "nothingness". Through "compliance" and "humbleness", man can reach the state of "nothingness", which Zhuangzi named it "Enlightenment". Although 〈Mountain wood〉 is an extension of 〈Human world〉, but speaking of the content, 〈Human world〉 mainly stresses the skill of mental fasting and the endeavor to obtain the meaning of considering uselessness as usable. Except for expounding the meaning of considering uselessness as usable in 〈Human world〉, 〈Mountain wood〉even encourages us to forsake everything and return to the ideal world of built virtues through nothingness and compliance. Technically,fables、quotation and situational sayings, they consist both of the aforementioned and that still is the techniques Zhuangzi was most excellent at.
