Are the girls in Zhujiang Piano Factory tired?

Tired. Pearl River Piano Factory is a state-owned enterprise with good welfare, but it is quite hard and semi-assembly line. If you don't work overtime, it's a weekend. The salary is quite high if you work overtime. If overtime and piecework are counted together, it will definitely be tiring. I wouldn't have left if it weren't for my later career development. People who don't feel well can retire in it.
