In Shenzhen, Dongguan and Zhuhai, the wages of grinders in plastic mold factories in these three places are basically the same as those in Suzhou, and so are the science and technology industries. The richer the technology, the higher the salary. Because you have two and a half years of work experience, your salary is generally around 3000-4000 yuan. However, there are usually extra bonuses. In fact, the wages of factories vary greatly. Even in the same factory in the same place, different bosses have to pay wages.
