Reference books can generally be bought in bookstores. If you have real questions, you should buy them at school. If you are out of town, you can call Zhejiang University and send the money. After that, Zhejiang University will express the real questions to you. Usually 4-5 yuan.

I don't know what professional questions you want. If it is a real question of liberal arts, I have it, because a real question of Zhejiang University is divided into four groups: A, B, C and D. Candidates can choose any group to answer (except some professional requirements), so after buying a real question, a paper will have many professional real questions. If you want the real question of liberal arts, then I can help you solve this problem.
