What manual labor have you done? Can you tell me something about it?

The beaded shop opened by my friend is the kind of beaded shop that makes door curtains, vases and other handicrafts. He mainly sells materials, and sometimes when someone wants to customize handicrafts, he takes orders and completes them by hand. Sometimes too many orders will be handed over to others to pay labor costs. The person who takes the order can't make much money and is still very tired. Dozens of dollars a day at most.
