1, Mathematics major is Mathematical Analysis, edited by Huazhong Normal University and Fudan University (Higher Education Press). We have studied the Fudan version, which is very comprehensive and detailed.
2. The general engineering course is advanced mathematics, the content is similar to that of mathematical analysis, but it is not as deep as mathematical analysis. Mathematics majors pay more attention to proving why and how the formula came from, while engineering majors pay more attention to its application in corresponding disciplines. Such as economic and physical applications. Generally compiled by Tongji University (Higher Education Press).
Supplement: There is also a book called "Calculus Course", which is a Chinese version of Russian mathematics textbook translation from Higher Education Press. It's also very good and comprehensive.
I hope it helps you.
