Is there a night shift in the kitchen?

No.

Chinese chefs do not need to work night shifts. Most of the working hours of Chinese restaurant back chefs are from 9 am to 2 pm, and from 16.30 to 21 pm. Each Chinese restaurant is slightly different, but it will not be too different. , the chefs are all on duty in turns. You may get off work late only on the night you are on duty, but at most you will leave a little later than others, but you will not be on night shift.
