Source: Seven quatrains for Father.
Children are determined to go abroad, or they will not return if they fail. Mulberry fields don't need to bury bones, and life is everywhere.
My child made up his mind to go out of his hometown and vowed not to come back without success in his studies. Why should he bury his body in his hometown after his death? Life is full of green hills where he can bury his body.
Literary appreciation:
This is a typical lyric poem. The poetry expressed in the first two sentences is vivid, magnificent and powerful. With the swan song of "If you don't become famous, you will never return", it shows the author's determination and great ambition to study.
The last two sentences dig the above poem into a deeper artistic conception, and use the method of first denying and then affirming to vividly describe why the bones should return to their hometown after death and the poetry of where life goes. From the poem, I naturally gave a deep sigh, which was inspiring.
