I don't think a general statement is fair to make. I met many Chinese people, and they are so different the one from the other!! Some have impressed me in a very very very positive way - very hard working, honest, very polite, friendly, warm, or smart - and others in a very negative way - steeped in crime, rude, rough, spitting on the floor, etc. Surely just like for every other group of people: there is variety, some are very nice, some not so nice. Some pleasant, others not so. A generalization is totally unfair, in my opinion. : )

Chinese people make the profound meaning on what they said. You might have some time to understand them.

I´ve never talked to Chinese people, but I think they are a bit serious but not very different to me, obviously each one with its own culture and customs.

I'm an American, so i can only speak for some Americans. Chinese people are just like any other people and people will more than likely not be able to tell that you are specifically from China, they will only see you as Asian, and they will probably treat you just like anyone else. There is a stereotype for Asians that they are all very smart and great at math, but cannot pronounce many English words correctly, and are serious about their education. Asians are thought to be incredibly polite, honest and enthusiastic. Another stereotype would be that Asians can be cheap, but this isn't nearly as popular to believe. And to be honest, it depends on where you go in America that people will see differences between you and others. Where i am from, Chinese people are not common, so you may get asked where you come from, why you are there and how it feels to be in America. But if you go to a more populated city (like Seattle or Los Angeles) people will more likely than not ignore you because there are many more foreigners and Asians.If you were to go to a place with very few to no Asians, you may get a lot of hate or rude comments. Some people will look at you and only see your country and they will take out their anger towards your government or culture out on you. Don't be afraid though, this probably will not happen to you :)
