These textbooks you mentioned, the new and old versions of the East and black Russian (college Russian) are professional textbooks, which are not suitable for self-study. Relatively speaking, it is more suitable to travel around Russia, but it is more effective to have someone to guide. The New Oriental Edition is still in the process of practice, and some problems need to be corrected. The content of the old version is somewhat outdated, which has both advantages and disadvantages.

In fact, what textbook you choose depends on your own learning purpose. If you are going to work in Russia, it is more appropriate to travel around Russia. If it is aimed at domestic exams, the Concise Course of Russian for New Universities published by Higher Education Press (starting from zero for adults) is more suitable.

The above textbooks can be bought in Xinhua Bookstore, and online shopping is more convenient.
