I have been back for three days.
As Singapore is on the equator, I experienced a sudden change in temperature on my way home. In my city, Shijiazhuang, the temperature is about 0 to 10 degree celsius.
In Changi Airport (Singapore) there was a group of white people sitting around me. One of them seemed to be interested in what I was doing- watching the match of Man Utd. against Chelsea! He tried to talk to me. After he made sure that I could speak a little bit of English, we had a short conversation.
Then I knew that they were university students from New Zealand and was going to Peking University for some kind of visiting. I told them that Peking University is one of the best universities in China and they looked amazed.
O, besides that, they asked me about the access to facebook in China. Yea, facebook, twitter and Youtube are blocked in China, Gmail and hotmail are available. Foreign friends always ask this, haha.
That's it, try to write more when I am free....
