When introducing yourself, don't look at everyone, look forward, stare at a place where there is no one, and don't bow your head. You can look up a little.

2. You can make full preparations in advance to prevent bad results. Here are the prepared templates:

(Nodding slightly) Good morning/afternoon/evening, everyone! My name is xxx (name can be meaningful), my personality is xx (introverted or extroverted), I come from xxx (hometown characteristics), I usually like xxx (hobby) and I am good at xx (specialty). I'm glad to be friends with you. I hope I can make progress with you in the future. Thank you! Don't say that you failed in the college entrance examination and came here. Don't be too silent, and don't brag about your past. )
