It's simple. You're going to curry favor, and don't invite the leaders to dinner on holidays. The workshop director doesn't have to call. Please eat in your name, but be sure to call your relatives' old classmates. The name of eating is to ask your relatives' old classmates to call your department manager. Aren't they old friends? Speak nice, but let your relatives' old classmates introduce you at the dinner table and say that you are his nephew. Please pay more attention to your department manager in the future! ~ as for whether he cares after dinner, it depends on your performance at the dinner. As for how to take care of it, whether you can find a good job after the internship depends on how far you can go with the department manager in the future! ~
