Confucianism teaches foreigners Chinese. Is this job okay?

I have a friend who is also Rusen's teacher of Chinese as a foreign language. Headquartered in Shanghai, this training institution has branches in Wuxi, Ningbo, Wuhan and other cities. This is a very reliable school. It is not so easy and fast for foreigners to learn Chinese at once, but it requires a certain training process, theoretical courses, practical courses and pre-job training. In fact, if you are in Shanghai, you can go directly to school. I'll believe that when I see it. My friend has been working for almost a year.
