I've been there. It's bitter and tiring. I stay up late and work overtime every day. My old friends in my dormitory are all unqualified foreigners. No matter what night shift you take or watch TV or listen to music, everyone who speaks is very noisy, unable to sleep and has a headache. Some things are harmful to human health, and I can't work in this field for a long time, especially for women. My friend stayed in it for a long time and was ill in hospital. I can't do anything heavy now. Each dormitory has air conditioning and two electric fans. I can't take it anymore. When you have a cold, you should volunteer to work and clean up every week. I only rest on Sundays and sometimes work overtime. The low salary is basically due to overtime. The food in the canteen tastes terrible. I don't have to do my own laundry. It is forbidden to wash your clothes in the dormitory except underwear and socks.
