Forget teaching. MOE scale down hiring from 3000 a year to 1000 a year. Plus recession coming, a lot of fresh grads and jobless are applying. Interviewees are given a topic and are expected to demo their teaching skills during the interview. You choose the wrong to enter.

Try full time tuition for flexible work life balance. You control your time. I done it for two years and it was fun. 3k to 4k per month but a lot of free time.
