And, sophy, it's not so easy to communicate with people from different culture. 
I think what we can do is speak more and try our best to let them know what we're thinking. 
Now I only know do this and don't know if it is useful. 
But ,everybody——no matter from China or other countries——has a kind heart. I always believe that.^^ 
So, come on! Let's working hard together~!

Now I know, everything begins hard.
But when you put your heart into what you're doing and work hard, you can achieve something. 
Thank you all for your encouragement, I won't lose my hope. 
And I will try my best to make my opinion clearly when communicating with others.
