The specific bibliography will be on the graduate website of their school.
However, some schools do not specify books, but will give the specified scope, that is, the outline.
In addition, textbooks may change. For example, in the theoretical physics of Beijing Normal University, 13 suddenly changed the examination subjects. Even the reference books have changed.
I just helped you see the math department of Shandong University, and there really are no reference books. But they have specified an outline. Just review according to the outline.
