The way to treat guests is really simple. Well, it is not clear whether the guests are friends, elders (I mean friends of parents) or relatives. Let's explain it in detail. Personal views are for reference only.

1 since friends are friends, they naturally won't be too constrained to go home. If you need anything, your friends can tell you directly. If the relationship is good, I won't mind these.

When the elders get home, the first thing is of course to pour tea. Hehe, anyway, I am like this, and then remember to be polite when answering questions from my elders. Well, I believe you should also know what to say and what not to say. . . . Then it is summer, and the elders can cut a watermelon when they go home. Well, if it's Chinese New Year, they will definitely bring melon seeds and peanuts or something. Hehe, it seems a bit complicated.

For relatives, well, the first thing to do is to pour tea, and then you can chat with relatives.
