What experiences did you have in choosing a tutor when you were in graduate school?

I was so excited when I was admitted to graduate school. There are three candidates when choosing a tutor. One is a recognized academic professor, who has very high requirements for students' academic level; One is a young associate professor who has just started teaching graduate students. The last one is a professor and doctoral supervisor. Rumors in the Jianghu are very generous and good to students. They often take students to high-end restaurants. At that time, Modi (himself) chose the last generous teacher after consideration and called it "double teacher". Teacher Shuang told me in the email: "Mop, you should be prepared psychologically, it will be very bitter." At that time, I thought it was the teacher's rhetoric, so I replied, "I can bear hardships." Since then, Modi's graduate life has officially begun. I entered the school in September and didn't get the tutor's grades until mid-June. 10. I went to see my tutor for the first time. One day, a girl called me and said that the teacher asked to meet. Several other people and I rushed to a hotel box, which was very imposing. As soon as I entered the door, I found that everyone had arrived, and there were four seats left. After sitting down, I realized that it was not the teacher who wanted to invite us to dinner, but the daughter of one of his friends who wanted to take the postgraduate entrance examination and came to visit the pier two years in advance. The teacher asked us to come, one is to increase the atmosphere, the other is to introduce the postgraduate entrance examination experience, and the third is to accompany the wine. When the mop first came to this occasion, I couldn't help feeling nervous. Although the amount of alcohol is ok, it is not easy to show off. This friend may be an official or something. He is not very polite to us and always finds fault with us. It doesn't mean that no one can talk, that is, he can't drink. Teacher Shuang also reprimanded me, saying that I don't even know the basic toast etiquette, so I should pay attention to it in the future. Actually, it's not that I don't understand. It's just that toasting habits vary from place to place. It's embarrassing to lose face in front of so many people. High-end wine and high-end food are boring to me. I don't know how the rumors in the Jianghu came from before. I didn't come to invite students on purpose, but to make me laugh. I don't feel comfortable in this upscale place.
