The whole poem is as follows: the teenager leaves home, the old man returns, and the local accent has not changed. When children meet strangers, they will smile and ask where the guests are from.

The literal meaning of the whole poem: I left my hometown when I was young and didn't come back until I was old. Although my accent hasn't changed, my hair on my temples has turned white. Children in my hometown don't even know me when they see me. They asked me with a smile: Where did this guest come from?

Appreciation: This is a sentimental poem about living in a foreign land for a long time and missing my hometown. I wrote it when I first came here, expressing my feelings of being hurt by a stranger for a long time. In the first and second sentences, the poet was in a familiar and unfamiliar environment in his hometown, and he felt quite uneasy all the way: he left home in his prime; When I got home today, I couldn't help feeling. The first sentence summarizes the fact that you have been away from home for decades with sentences like "running away from home when you are young" and "going back to your boss", which implies the feeling of hurting your boss. The "bangs" in the second sentence is the top of the previous sentence. Write down your own "boss" status in detail, and set off the changed "bangs" with the constant "local accent", which means "I don't forget my hometown, can my hometown still recognize me", thus paving the way for the following two sentences to cause children to be unfamiliar and ask questions. Three or four sentences changed from an emotional self-portrait to a dramatic scene in which children smiled and asked questions. "Laugh and ask where the guest comes from", which is just a faint question among children, so stop here; On the poet, it became a heavy blow, which triggered his infinite feelings. In his later years, the sadness of the opposition between subject and object was included in this seemingly dull question. This is the place where the whole poem ends quietly, but the meaning is like an empty valley, full of sadness and boundless.
