Appreciate the artistic effect of "self" and "emptiness" in the poem "From Shaxian to Longxi, after Quanzhou Army, the village was empty because of stunts"

The word "zi" echoes the word "empty" from a distance, showing that everything in the countryside was left to fend for itself at that time, and no one cared about it. This shows the tragic scene of "a thousand villages are like cold food", and at the same time implicitly expresses the poet's anger at the atrocities of Quanzhou army.
