Vantaggi
Good salary in the long run, if you have the skill to negotiate and also raise this request. If you do not raise it or raise a complain about salary, your salary will not increase or change. Possible option to be awarded TUP (similar to shares of the company), which in the past was great, but given their recent company performance the amounts received is no longer as lucrative.
Svantaggi
No career progression if you are not Chinese, you often work with a lot of incompetent people who will be given more opportunities for growth and learning than you. As a non-Chinese you will often feel like a second class employee, you will always be informed last of any changes, they will always questions you and doubt you. Strong Chinese culture, which can be difficult for many to adapt, even in branches in Europe. Efficiency is non existent.
