Today I asked my foreign teacher, "What is your impression about the Chinese?" He told me that his college has a lot of students from China. They talk loud, leave rubbish everywhere, and call him any time they want. His answer made me so sad. I just want to say, not all Chinese are like that. They are polite. They are modest. (OR, They understand modesty.) 
By the way, I want to ask you a question. What is your impression about China and the Chinese people?

The punctuation is difficult to learn. Pay attention to how we use it. Sentences end with a period (.) or question mark (?) or exclaimation point (!) right after the last word without a space before it. There is one space after the . or ? or ! before starting the new sentence. New sentences always begin with a capital letter.

Please, please, please don't use "R" and "U" in place of "are" and "you". I know that it looks like that's the right way to do it when you read some things that people write but they are very informal and not proper English. If you are trying to learn English you shouldn't use these.
