It depends on the class time. If you are a minor, take more classes and your salary will be higher.
However, if you are not English in math, physics and chemistry, you are basically poor. Any young teacher who teaches math, physics and chemistry English in Anqing No.1 Middle School can be a tutor, with a monthly income of 1-20000, tax-free. So basically buying a car, a big house or even a villa is not a problem.
Those who teach other courses can barely buy a second-hand house in Anqing.
