The first two chapters are the first layer, writing that my parents have worked hard to raise me.
The middle two chapters are the second layer, which describes the son's pain of losing his parents and the parents' deep love for his son.
In the last two chapters, the third layer inherits the last two sentences of the fourth chapter. The poet blamed heaven for his great pain, because he could not support his parents and repay them with great kindness. He blamed him for his impermanence, which took away his parents' lives and made it impossible for me to report and express my misfortune.
The alternate use of Fu and Bi Xing is a major feature of this poem. Feng Fang's "On Poetry" said: "The first three chapters of poetry are all given first; Four chapters are also given; The five or six chapters are all prosperous times. " The last two chapters should also be said to be "getting rich first and then getting expensive". The three expressive techniques are flexible in use, echoing back and forth, lyrical and ups and downs, conveying loneliness and sadness, which can be described as a smooth jade plate with strong artistic appeal.
