1. Two people don't know each other, so we must find a topic to talk about. In fact, sometimes people like food, so when chatting with each other, we can choose a special food to start.

2. A successful chat will make people feel unfinished, and sometimes they even want to let the other person meet you. When you talk, you should pay attention to where it ends. When two people are chatting enthusiastically, you must not end the topic.

3. If you don't know how to get in touch when chatting with you, you can ask the other person for help. Of course, it's not substantive help. It's just a language method. For example, if you want to eat something, but don't know where to go, you can ask the other person.
