What can I do to earn 100 a day?

Generally speaking, in southern cities, one day 100 means a monthly salary of 3000, which I think should be very common.

If you are in the north, it is higher. If you don't have a high diploma and can't find a better job, you can do some small businesses, such as small boutiques (mainly small gifts for junior and senior high school students) or snack beaches. If you are still young, you'd better continue to go to school or learn a trade, and you must learn fine skills. It is not difficult to achieve 100 one day after coming out.
