What is the treatment of Shenyang Kechuang Chemical Co., Ltd.? I'm a maintenance major. How much can you earn? Is there a year-end bonus?

Basic salary 1800 plus post salary and year-end bonus. How much accommodation is uncertain: heating expenses are reimbursed and local accounts are not allowed to work in shifts. Three shifts are two shifts, with white shifts at 8:00- 19:30 and night shifts at 19:30-9:00, which means going to work every day and not sleeping at night. . I found another job completely.
