My Experiences In The US

Before I came here, I thought California is very worm all day . But it is only worm in noon , and cold in morning and night.
Here residents are very friendly. When you see a stranger , he/she will give you a big smile. it make you feel wormer.
I saw some girls dance on the campus. I have not seen it in China. There is the difference between US and China .
The type of class in China is bigger than the type in US. In China, there are less than sixty persons in one class, but here no more than fifteen.
