Where are you from? There should be classes in cities. There are many classes in our city (Yanji City, Jilin Province). The basic primary class ends in two months and goes to 200 yuan every month. There are also intermediate classes and advanced classes, depending on the level. It's also two months after class.

There are also technical secondary schools and junior colleges specializing in Japanese, with two years in technical secondary schools and three years in junior colleges. The tuition fee is about 3000 yuan per year, and the certificate will be given after graduation. But I feel that its certificate does not contain much gold.
