What is the treatment of Nanjing Taitong Technology R&D? Is it formal?

Hello, the salary of Langli Lance Technology is not very high. I worked overtime for the first three months after I went in, and my salary was only about 3500 yuan. Lance Technology is a famous sweatshop, and its working hours are very lifeless and inhuman. The dormitory is a room for 8 people, which is relatively crowded; Resignation is troublesome. Some of my friends have left. It is suggested that if there is a better unit, don't enter this cheating enterprise.
