No , this is the second time . But I also feel bad because of the lower pressure and the jet lag .

Oh , I am sorry to hear that . Take it easy . It will be OK soon . You see , I take this long-hour plane frequently , but the jet lag still makes me uneasy .

Oh , that's too bad . Do you get a good knowledge of China ?

user
Yes , whenever I think about China , I'd see the Tian'an Men Square . China is a very beautiful country . And I've seen many landmarks in China but I like the Great Wall most .

All of the Chinese are proud of the Great Wall . And it was built before the In dynasty near Shan Haiguan-the First Pass in the World .
