I want to find a job related to chemical industry in Changzhou, and I can also be an operator. What were the chemical plants in Changzhou in the past?

I work in chemistry in yabang, and the salary of operators is generally 2500-2700. Working hours are from 8:00 a.m. to 7: 00 p.m. in the day shift, and from 7: 00 p.m. to 8: 00 a.m. in the evening shift. The day shift is closed on the third day and continues on the fourth day. Generally, there are 3-5 days of public holidays every month. If I stay, I wonder if there are any dormitories available. Apart from a soymilk machine and a battery oven for the New Year, I don't even have a hair on the Dragon Boat Festival. There was a trip before, but it was cancelled the year before last. There used to be a New Year's Eve dinner, but it was cancelled last year. I don't know what to cancel in the future. Anyway, it is getting worse every year.
