Formal:
* 再见 (zài jiàn): This is the most common and versatile way to say goodbye. It literally means "see you again" and can be used in most situations.
Informal:
* 一会儿见 (yī huìr jiàn): This means "see you later" and is more informal than 再见.
* 待会儿见 (dài huìr jiàn): This is another informal way to say "see you later" and is very similar to 一会儿见.
* 下次见 (xià cì jiàn): This means "see you next time" and is a bit more casual than 再见.
For specific situations:
* 一会儿聊 (yī huìr liáo): This means "talk to you later" and is a good option when you're leaving a conversation but plan to continue it later.
* 回头见 (huí tóu jiàn): This means "see you around" and is used when you expect to see the person again soon.
The best way to say "bye for now" depends on the situation and your relationship with the person you are talking to.
