First everyone knows Wulong here I think it is also because of the three bridges of nature, but then with Dad where to wait for the TV variety show, Wulong Tiankeng ground seam these characteristics of the address fully displayed. This is also Wulong's unique karst landform. Many friends come to Chongqing. In fact, I will recommend them to come here to play, but everyone only cares about the mountain city and encounters hot pot again, and ignores the beautiful place like Wulong Tiankeng and ground seams in Chongqing.
