When I set foot on this kind home, the children saw me and didn't know each other. They smiled and asked me, "Where are the guests from?" Later, it was used to express a kind of sadness when people who had been away from home for a long time came home.
The poet left his hometown when he was young, but when he came back, although the local accent had not changed, his hair was already gray. The children in my hometown didn't know the returning wanderer, and asked with a smile where the "guests" came from.
The speaker is unintentional, the listener is intentional, and the innocent laughter of children hits the poet's heart.
I just haven't been home for a long time. Once returned, even if the local accent has not changed, it can only become a passer-by in the eyes of hometown people, and it can be seen that hometown has long been a place of vicissitudes of personnel metabolism.
After this question, how embarrassed and emotional should the poet be? However, the poem came to an abrupt end, leaving readers to ponder the ups and downs in the poet's heart. The poem seems to have a relaxed tone, but in fact it is implicit and deep, intriguing and sighing.
