Secondly, for those who have no teaching experience, they need to obtain some certificates, including short-term training certificate and master's certificate in teaching Chinese as a foreign language. As for the choice of short training courses or postgraduate entrance examinations, it should be chosen according to personal circumstances. If you take the postgraduate entrance examination, you will risk failing the exam, and then you will face the pressure of choosing a job. You should know that there are all kinds of people competing in the field of teaching Chinese as a foreign language, from high school education to graduate education. Therefore, getting a master's degree will not add much weight to your employment, but it will waste two or three years of youth and lose your age advantage.
Thirdly, as far as teaching Chinese as a foreign language is concerned, its development prospect is not optimistic. If you can't get a stable teaching position in colleges and universities, you can't continue to work after your thirties. It's hard to imagine a man in his forties and fifties still teaching foreigners Chinese here and there. But if you want to get a stable teaching position in colleges and universities, you must get a doctorate and have quite fruitful research results. In this case, the difficulty will be greatly improved.
To sum up, first of all, I don't recommend you to enter the profession of teaching Chinese as a foreign language. Secondly, if you have to enter, you can only consider temporary work, and it is enough to get a short-term training certificate.
