Kunming Branch and Kunming Salt Mine get about 1800 after deducting five insurances and one gold;
The salary of Tianye Chemical is a little higher than that of other cities, which is about 1500- 1700 at present.
It's ok to come in and learn something, if it's a chemical major. Other majors, the things you learn are too simple, which will not help you to change your job and develop better in the future!
I hope it helps you!
