Why does Xiangcheng Shoes Co., Ltd. recruit people all the year round?

Xiangcheng Shoes Company is recruiting people all the year round because of its high employee mobility. Xiangcheng Shoes Co., Ltd. basically works overtime for two hours every day, and promises to work for eight hours, and actually works 10 hour. There is no money for overtime work, and I often find excuses to say that I can't leave work until I finish my eight-hour workload, which leads to many employees who can't stand to resign and have a high turnover rate, so they are recruiting people all the year round.
