How much can an underwear factory that has been operating for 10 years earn a year?

The annual profit is about 300,000-800,000. If it is a second-and third-tier city, the profit may be more.

Being an underwear factory is very profitable and has a good prospect, because people now need to wear underwear very much, and they have to wear underwear every day when they go to school and come home from work to facilitate their work and housework, so there is a great demand, especially for people living in urban buildings, who have to wear underwear when they come home from work, so it is very profitable to process underwear. Those who have the ability must open such a processing factory.
