Hangzhou Hangzhou West Flower and Bird Crafts Market is it true or not that Chinese calligraphy and painting companies recruit people to do manual work?

I went with my friends, in Zhongshan Garden, in the residential building. After I went in, there were paintings everywhere in the room. Many people are still doing it, and some men ask the boss about the specific situation, but they mentioned that they would pay the tuition in 500 yuan, and then they agreed. After completing 20 pairs, they will give 300 yuan a bonus, including the refund of 500 yuan's tuition. My friend doesn't believe it. One of the bosses (a grandmother in her 60 s) has a bad attitude and says she doesn't want to work. There is no mention of paying tuition fees in 500 yuan on the Internet. Is this a lie? And I don't know how long it will take them to complete the 20 paintings that they have stipulated that can be recognized by them. Maybe we think we are doing well, but what should we do if people say no? . . Many recruitment websites have posted their jobs. I know it's been two years now, but I don't know if it's true or not. Anyway, I was a little disappointed after reading it last time. I'll still believe it if I don't charge 500
