There are many beaded and paper carving handicraft shops in Jinan. Is it credible to recruit part-time jobs?

Not credible. Usually they pay or buy some raw materials, teach you, and then buy finished products at a high price. But after you spend money to learn, they don't recognize your handicrafts, saying that the quality is not up to standard and can't meet the requirements of market sale. Anyway, they bought it for free or at a low price for various reasons. Let's not do this. Think of something else
