I think there are four kinds of interests in Chongqing.First one is to enjoy the city view,the second one is the three gorges of Changjiang River,the 3rd one is the Chongqing food(be famous for it's spice taste),the last one is the remaining buildings of the times of revolutions.
Dazu Stone Carvings
Situated in Chongqing municipality, Dazu is know as the Hometown of Rock Carvings. Cliffside carvings born in the Tang and Song dynasties spread all over the county, with as many as 74 cultural and historical relics under protection of the state, province or the municipality. The carvings consist of more than 60 thousand figures, most of which are concentrated in the two big grottoes, Beishan and Baodingshan, both under state protection.
