Shocking personality, self-introduction

It's disgusting to brag about something, and it's annoying to talk too long in three minutes. Briefly introduce your primary school name hobby and tell a few jokes to enliven the atmosphere. You can also talk about your nickname and interesting stories in the past. Be concise, don't make a long speech, avoid commenting on others, have a better mental outlook, stand up straight, hold your head high, try not to move too much, and look into everyone's eyes. In short, generous and natural classmates will think that this person has a good temperament and is naturally impressed. Don't be unconventional, you will go too far if you don't master it well.
