According to the regulations of China Municipal Government, there is no fixed age limit for directors. The age of directors in different regions and departments may be different. Generally speaking, the age requirement of directors is in the range of young and middle-aged, usually between 35 and 55 years old. But this is only a rough age range and does not represent all situations. In fact, the specific age requirements will depend on different conditions and policies. The specific situation also needs to consult the relevant documents or policies of the local government to obtain accurate information.
