How about the book Introduction and Improvement of Standard Japanese: Speaking Japanese as soon as you learn it?

Learning the new edition of Japanese communication between China and Japan is very detailed and practical.

And if you don't want a teacher, watch the TV lecture on the new standard day, which was told by Mr. Ren Chuanhai and Mr. Komori.

In fact, I found that everyone agrees that you can watch his lecture without reading a book. )

Come on, as long as you study hard, you can learn well. Books are not the most important thing.
