Dressing appropriately when meeting is one thing, followed by your tone of voice and your professional behavior, of which the latter can be said to account for 58%. At the same time, you should take the initiative to explore the tone and behavior of each other's personal hobbies, and try to imitate each other's behavior naturally, which will narrow the distance between you, but remember to imitate it properly and naturally, otherwise you may get twice the result with half the effort.
In addition, I suggest reading more books on this subject if you have time.
All right! Good luck! ! ! ! ! ! ! ! ! ! ! ! !
