There are Chinese teachers and foreign teachers majoring in Japanese in Nasi Foreign Language. The basic should be a Chinese teacher, professional and amateur. The major leagues have three months. They help you make study plans and goals, and generally you can achieve them. That's my major. From 0 to the current level 2, the tuition fee is about several thousand yuan. Amateur usually lasts two months to one year, and the tuition fee ranges from more than 500 to more than 2,000. They are all teaching points of Shantou University. I think they are more reliable and the teachers are very responsible.
