How to greet your elders when you go out

in general, it is the elders who ask the younger generation questions. If the younger generation has grown up and lived independently, they can also take the initiative to care about their elders, such as their health, family situation, busy work (life after retirement) and so on. Greeting is a polite chat. Generally speaking, we don't pay much attention to the content of the chat, as long as we show concern and are happy to meet.
