Does Lianlong New Materials work overtime?

Lianlong New Materials doesn't work overtime. Because Lianlong New Materials implements large and small class system, Lianlong New Materials does not work overtime. The full name of Li Anlong New Materials is Li Tianjin Anlong New Materials Co., Ltd., and the company's attendance system is large and small classes, that is, large classes are 8: 00-16: 00; Small class 16: 00-22: 00.
