This key depends on what department and tutor you are. For example, in the department of automation, papers are required, and the core is enough. There is no such requirement at present. If you can't publish it, as long as you can write a big paper; At the same time, the paper can only be issued at the first level, otherwise it will not be issued, which means that the quality of the paper is now higher. It should be said that the postgraduate education in Yanda University is becoming more and more formal.

As for the tutor, it's really a personal problem. Some teachers are very good. Students work hard, teachers pay, and finally teachers return all the money. But some, that's quite disgusting. It depends on the teacher you are looking for!
