Regarding mathematical modeling, there is a classic textbook published by Jiang Qiyuan in China, which may be difficult for beginners, but it is really classic and recommended. In addition, I recommend a foreign mathematical modeling textbook, which is published by Machinery Industry Press. It's already the fourth edition. Although I haven't read much about this book, other students who are engaged in mathematical modeling around me think it is better, so I recommend it. In addition, if you engage in mathematical models, a related book of matlab is essential, and the programs of basic mathematical models are all completed by matlab.

As for the English textbooks of the Department of Mathematics, our math classes are basically bilingual, but I'm not a math major, so I'm afraid the recommendation is incorrect. However, generally speaking, foreign textbooks are classic. Personally, I have compared foreign textbooks at home and abroad, and think that foreign textbooks have clearer ideas, while domestic textbooks may be more suitable for exams. If you want to have a deeper understanding of mathematical derivation, I suggest reading foreign textbooks, but if you only take various domestic textbooks.
