For example, you can talk about your hobbies and yourself, what activities you like to do at ordinary times, or ask each other what they like to do, and maybe you can finish things together in the future. If it is suitable for your relatives and elders to chat, you can't talk like this. You have to talk to them about medical and health issues in another way. You can add some extra knowledge. You can make your relatives and elders happy. You can talk about some practical things, that is, some small things that happened to you recently or in the past. The easiest thing to talk about is to talk to the elders about things between the younger generation. This is also the favorite words of elders. Talk about some living habits and eating habits of the younger generation in life. If it's suitable for chatting with old friends you haven't seen for years, you can choose to chat with them about some old things.
Some interesting things that happened together. You can also talk about a series of work problems, such as the recent situation, where to find a job and where to go to work. Maybe you can ask a friend. You can also talk about the appearance and facial features of some of your old friends. See if the change before is big or not. The most important thing is to talk about each other's parents, wives, children, elders, recent physical condition or study status. I think these are the most useful topics. Then you can sit down for a meal and talk about the stupid things you did before. I think this is a topic we can talk about during the Spring Festival.
