A friend of mine used to work in the construction industry. Because young and emaciated, the construction industry felt particularly hard, so I chose to change careers and started interior decoration. This industry needs skilled workers. He doesn't want to be exposed to the sun outside, but works indoors. Moreover, it is inextricably linked with the construction industry, and he can handle it with ease. Now he is a famous local contractor.
So if you don't want to engage in the construction industry, you can choose interior decoration.
There are several other industries that can provide you with reference.
1 building materials market, there are more people repairing houses now, and the demand for building materials is also relatively strong. You can open a building materials store, and the business must be very hot.
Open a hardware store, and someone has done market research. A man wanted to buy some nails, but he ran everywhere and couldn't find a hardware store. So the business of opening a hardware store is particularly good.
