First, you can set up a supermarket to sell fruits and daily necessities. This is really profitable, especially fruit. People who come to the hospital buy fruit and milk. I recommend you to do a small supermarket, and you can also make money with your baby.

Second, catering, setting up stalls to sell lunch boxes, stir-frying side dishes and burning some soup. People in the hospital have to eat, whether they are patients or doctors.

Just these two, I won't suggest other ideas, after all, these costs are low.

To run a supermarket, I might add that you should also sell some medical supplies or things needed for hospitalization, such as diapers, toilet paper and chamber pot.
