How is like china mainland?

China is like a really big country,there will be endless place to go,you may say that you went to a certain city but ud only miss half the tour parts.
As far as i know you should check out Beijing and most of the northern parts,there will be many historical sight seeing whileas if you like shopping and youre really have the cash i say go to Shanghai,hongkong,shenzhen.And if you are in the southern region dont forget to go to Shaoguan,Guangxi province(the insect eating place),Yunan,it got really good site seeing place.
All in all i even havent been through many place,but its worth the visit.But before you go lemme tell you the the tour guides can be really cunning and will rob you by intimidating you to buy things and products.I am telling you from my experience and many other relatives who have been out there.
In the northern region like Beijing people can be really rude liked theyd be shouting at your face,ignore them,but i think that long back then maybe they got manners now .
