Take the liberty of analyzing, I hope I didn't offend you. It should be pointed out that there is no fixed job and no skills to win in the highly competitive market. Based on this guess, I have some personal alternative suggestions, hoping to help you.

2. Greening plants in cities or schools

3. boarding at the school gate or dormitory

4. Home Economics

5. Mobile catering car (breakfast snack night market stall)
