Agatha Foreign Language School is famous and has better teachers. Most of them are foreign teachers, but the tuition will be higher.

I suggest Japanese, Russian, Arabic (choose this if you are a man, not a woman) and Portuguese. First of all, forget about English. There are too many people learning English, and I believe you know a lot yourself. There is no need to study it specially. Secondly, you can learn any of the five Romanesque languages, namely French, Italian, Spanish, Portuguese and Romanian. There are too many people who study French, so they can only go to Africa to make money (except those who study in France, those who earn money at home, and those who have the ability to go abroad), and there are too few Italian companies in China, and too many people have studied in recent years; Spanish, you can consider learning this, but there are many people who learn it; Romania is relatively backward, and it doesn't have such close economic and trade ties with me, so it is difficult for you to find a job after studying. Then there is Portuguese, which is in great demand and few people learn it. Highly recommended.
