THe biggest tip I have for you is to stop by Shanghai. Shanghai by far is better then the three places you are going to.
Other tips include if you shop, which you should, divide the price they tell you by 2 or 3. They will try to rip off any tourist. If you do visit shanghai, brings tons of anti inch and bug repellent and bring something to enterain you on the plane ride cause its terrible. I go almost every summer for two months and I love it.
