Personally, I think Shi Jihuai's book is a little higher than other scores, but it is still within the acceptable range of mathematics students. Mathematics department can accept it, why not? The theorem in the book, think about it before going to bed at night and think about it in the morning, isn't it skilled?

As far as exercises are concerned, the exercises after Shi Jihuai's book have no answers, but the questions have answers, and they are basically sent home. What about the problem between getting started and ashes? Personally, I found that there is a book that covers almost all the solutions of exercises, and the complete solution of multiple-choice questions in mathematical analysis (Tsinghua's). This book seems to be gone, but there is an electronic version online.

As for Zhou's book, I feel a little competitive, so I should do altitude exercises later.
