If the university tutor doesn't answer questions and friends don't answer them, you can do this:

1, you can ask other relevant personnel.

2. If you don't return after adding friends, you must have missed it.

3, ask someone else for his phone number,

4, invite him to have a meal when you are free, and enhance your feelings together. It's easy to go wrong in the future.

I hope it helps you. Thank you.

Finally, I wish you a happy life.
