Before you want to be a teacher in whatever role , you need to be certified by enrolling in Teachers College at MOE go to
www.moe.gov.sg
Even you hold a certificate in Chinese language that does not mean your certification are recognized here. If you are PR thru spouse sponsorship then you need to be enrol to be a teacher trainee first. If you are on LTSVP then you need to change your pass to a student pass.
BTW SG is predominantly Chinese , so there is nothing special about your certification from China unless I am mistaken or if you hold a PHD in Chinese Literature or something similar.
MOE like all other agencies in SG is a pressure chamber to perform and deliver with minimum fuss and toeing the line. I have teachers in my family, pay is meagre but that is not the point as they love teaching.
