How much do I have to open in Changchun to get my wife to work full-time?

Changchun is a second-tier city and its overall consumption level is not high.

If you already have a house and don't need to pay in installments, you can earn about 5000 yuan if you want your wife to work full-time. If you need to repay the mortgage and so on, plus the monthly mortgage money, if you don't have a house, it depends on your personal planning. Buying a house in a few years and so on, of course, a life of around 5000 is absolutely enough.

good luck
