I think the best way is to go to the tutor's personal website to see what articles he has published. This personal web page is generally among the teachers of the college in the school, and the papers on it should be authoritative. Generally speaking, there are many English documents. Then look it up in the database according to the topic of the paper. Since you are a master, your school should also buy the corresponding database, just check it.

Cross-school, I think the key depends on personal ability. I have a sister from Zhengzhou University. He was admitted to a famous tutor of the Academy of Sciences and published a good article. Hmm. How interesting

It's easy if you don't have a personal website. Just go to the main database and search with the author's name to see what articles he has published.
