I am a boy and want to learn manicure. How long will it take to find a master with no basic knowledge before I can work?

This depends on your personal experience. Basically, it takes about 1 month. I guess you should have no problem. If you go to a nail salon to learn, I think the tuition will be cheaper. The nail salon here in Beijing recruits The academies are free, and some charge very little, with the maximum being around 1,000. You can consider going to the academy, which has a tuition fee of around 10,000.
