But what does it mean to see Kyushu and Kyushu in China sad?

"Kyushu" means motherland.

Original poem:

I know that when I die, everything on earth has nothing to do with me. But the only thing that hurts me is that I failed to see the reunification of the motherland.

Therefore, when the great Song Jun team recaptures the Central Plains, you will hold a home banquet ceremony. Don't forget to tell me the good news!

Translation:

I know that when I die, everything in the world has nothing to do with me; The only thing that makes me sad is that I didn't see the reunification of the motherland with my own eyes. Therefore, when the imperial army regains the lost land in the Central Plains, you will hold a family sacrifice. Don't forget to tell your father the good news!

Extended data:

Xiuzi is a quatrain written by Lu You before his death and the last poem in the poet's life. At this time, Lu You has been retired for more than 20 years and is an 85-year-old man. Knowing that he was going to die soon, he borrowed his son's will with regret that he could not see the reunification of the motherland before his death, and wrote about his concern and attachment to state affairs, showing ardent patriotic feelings.

The first sentence of the poem "Everything is empty after death" begins with the word "death" and humanity. When a man dies, he sleeps in a grave ignorant and carefree, and everything in the world has nothing to do with him.

It seems to be broad-minded and carefree, but the second sentence in the poem, "I am sad but I can't see Kyushu", takes the word "Dan" as a turning point, and writes a paragraph that I will never forget: I can't close my eyes when I am dead, even though the motherland has not been reunified, the people in the vast area north of Huaihe River are still living in dire straits. This tragic feeling is the natural and true expression of the poet's heart.

The third and fourth sentences, "Julian Waghann concentrated in the north, and the family sacrifices are never forgotten", are full of hope and confidence in national unity and show the poet's eternal love and loyalty to the motherland.
