Chen Jian Mathematical Machinery Industry Press and beijing institute of technology press are the same book with the same content, but the press has changed, and there is no mechanical edition this year.

The Mechanic Edition is the latest edition recommended by the author Weibo, and the foundation of the mathematics volume and the high score guide have been comprehensively improved. Mr. Chen Jian uses the Machinist Edition in his lectures, and there are other series of books, all of which are continuous, and each book is closely related to the high score guide (there are low-priced courses available for purchase).
