The company is constantly let employee firefight and has never conducted a proper review of its processes. Every day is spent dealing with urgent and ad-hoc issues. The China departments will call you directly without any prior notice. They work on a 996 schedule and have no respect for the time of overseas employees. When you inform them that you have finished work for the day on 6pm, they think you are being difficult if you don't work until 10pm with them.
