This Ruan Ji is a pure liar. Every day he will urge you to pay. Whether there are classes in your school or not, he just arranges classes casually, falls in love with them, and then stops making up classes. A teacher has four to five classes. Anyway, I didn't learn anything when I went there, and my money was wasted. My friend's fate is basically the same as mine, so I warn you, you'd better think about it, the tuition is quite high, and you won't learn anything then.
