Who ever worked in Putian Tong Jia Tire? How is the treatment inside and how is the grade divided?

I have worked in Putian for three years, and the salary is OK. If you are a worker, it depends on your proficiency. There should be more than 4000, divided into first-class host and second-class host, depending on the workshop. It is the highest internal refining, and the preparation and vulcanization environment is better. If it is a technician, the salary is almost 3000 yuan. In short, the longer the working hours, the higher the salary, but it is very hard!
