"Advanced Algebra" was originally edited by the Department of Geometry and Algebra of the Department of Mathematics of Peking University, Higher Education Press.
Workbook:
"Advanced Algebra (Third Edition) Synchronous Tutoring and Complete Solution of Exercises" Xu Xianke Tsinghua Publishing House
"Advanced Algebra Postgraduate Teaching Plan" Xu Zhong [et al] Northwestern Polytechnical University Press.
Methods of solving problems in advanced algebra: Xu Xuke Tsinghua Publishing House
The above are basically very easy to use. I majored in computational mathematics, so we used the above textbook (studied for one year). I borrowed the tutorial book from the library myself. These three books are easy to use.
If you want to learn mathematics, you must learn group theory (abstract algebra course), combinatorial mathematics, fuzzy mathematics and graph theory. They are all very professional.
