The Chinese economy for thousands of years has been based on intense collective agriculture. Their culture, as you would expect, reflects that; family and community ties are very strong, and the interests of the collective are placed before the individual, even in their names. Will any of that change with the explosive growth of cities, and, if so, how?
The migration of younger generations to cities inevitably will lead to a fraying of ties between the generations, and to more emphasis on individual preferences and freedom. Some elements of the culture, such as the food, language, literature, and history, will not be impacted by this change, but rituals relating to ancestors will become less prominent, informal controls on individual behavior previously imposed by the community will have to be replaced by more formal mechanisms, and the government will have to create an effective welfare state in lieu of relying on the community to take care of its own.
