I had the experience of buying books on Taobao.

Generally speaking, you can ask the seller directly: Is this book genuine?

I looked it up on Taobao according to the title you provided. The original price is 350 yuan, right?

Think for yourself, 350 yuan bought 50 yuan or something, which is less than 1.5 discount. If it's an old novel, it's too cheap, but it's possible to buy a genuine one. But what you want to buy is a special lecture on the international judicial examination, which belongs to the examination. If you have ever bought books in this field in Exam.com, Joyo and Dangdang, you will find it impossible to buy such a cheap price unless there are some special sales activities.

If you want a genuine book, go to a regular online bookstore to buy it.
