And I am 27 years old.But now,I study at the University of Michigan as a visiting student. I will come back to China in August. After I came here, I found out I should study more English, but in China, I don't know more about that other than that I am honored to be friends with you!

Remember, after all punctuation (Periods, Commas, Colons, and Semicolons) you must leave a space. China, Chinese, English, and all such things must start with an upper case letter.
