I suddenly discovered a project that can earn over ten thousand yuan a month.

List home computer, appliance, and water/electricity repair services on Xianyu.
After receiving an order, clarify with the customer that there is a 50 yuan service fee for on-site visits.
When you go there and see the issue, just say it's unfixable and charge the 50 yuan on-site fee.
This way, occasionally taking a few hits, earning a few thousand yuan a month shouldn't be a problem.
