I think it is amazing . You can enjoy both the traditional Chinese culture as well as the vitality of a modern cosmopolitan city . The only thing I didn't enjoy was the subway .

user
was it that crowded ?
neutral

yes . There were always so many people . After taking the subway during the rush hour , you ’ ll envy sardines in their cans .
