What is the salary and workload of teachers in Southern College of Sun Yat-sen University?

as far as I know, the teachers and lecturers in our school are usually 7, ~ 1, years old, and they should be lecturers and doctors, and they should have good teaching experience and academic background. Generally, they have to attend more than 12 classes a week (full-time), but I don't know about part-time teachers. It seems that some part-time teachers only have three classes a week, and they have to take a school bus for 22 yuan, one and a half minutes.
