It depends on the level of the teacher's lectures and whether I am willing to study. If the other person's lecture level is really high, and he speaks well, and he is willing to take a fake course, and every class is taught, then 195 yuan 40 minutes is not expensive. I remember that in 2009, in the city of Beijing, the hourly salary of some high school information contest instructors was 400 yuan. Although it seemed incredibly expensive at the time, some teachers who spoke well might be worth the money.
