How to get along with leaders, including greeting, greeting and so on.

Neither supercilious nor supercilious, just ask "Good morning, XX is always good". Different identities, don't talk to the leader if you have nothing to do. Do your job well. The leader must talk to you, just say something nice, whether it's this or that. It's very kind of you to lead the way. Thank you for your concern. Never complain to the leader, even if you are unhappy, you can't tell him directly. Of course, direct leadership is another matter. In short, doing a good job is the first priority, and you should have confidence in yourself.
