The third and fourth sentences closely follow the meaning of the villagers' death, trying to render the desolation of Zhao Jun before and after his death.
The fifth and sixth sentences first say that the Emperor of the Han and Yuan Dynasties was fatuous, and then write that Zhaojun did not forget his homeland and returned home at night. The word "empty" is used here to highlight the depth of Zhao Jun's resentment and send the poet's sympathy.
The last two sentences convey Zhao Jun's resentment for thousands of years with pipa music. Poetry is implicit and euphemistic, which is thought-provoking.
