I agree with that. There's plenty to do even in Shanghai, if you consider the surrounding cities/areas as part of it.
IMO, OP should choose the cities/areas to visit based on their own personal preferences (e.g. cultures/histories, natural wonders, city skylines, culinary experiences, etc. or some combination thereof).
