Before paying 1, you must know who the teacher is and what qualifications he has, and listen to the teacher's class when necessary. Knowing the quality of a teacher is directly related to whether you can study smoothly and master pure Japanese.

2. See if there are any courses specifically for Japanese listening and conversation, or whether the training institutions attach importance to cultivating students' Japanese practical ability. Because you know Japanese, it is very important to speak Japanese, no matter whether the purpose of learning Japanese is to find a job for exams, to study abroad, or for interest.

Reasonable course fees do not mean good.

To sum up the above points, I recommend:

First, Chengzhi, the teachers in Dashikou, Jiangning are all very good.

Second, although cherry blossoms are more expensive, they pay more attention to the cultivation of students' ability.

Third, find a good teacher directly.
