There's no large-scale official building on the site after the Northern Song Dynasty. The county seat moved under the Jinzi Hill on the southern bank of the Yangtze River Yangtze River tour. Archeologists say that a recent study shows the county official site was hit by flooding and mud-rock flows during the Northern Song Dynasty. After that, the county official site had to move out of Badong. The exact time is not clear but thought to be no earlier than in the Southern Song Dynasty (1127 - 1279).

Nevertheless, Badong had its most prosperous time in the Northern Song Dynasty and thereafter declined. Lu You, a poet from the Southern Song Dynasty, described Badong County China vacation deals in his Travel Notes to Sichuan: "The county is depressed: only some one hundred families live there. The houses are all made of thatch grass, not a single tile."

Li Qingrong, explained that the governors of all dynasties did not support the development of the ethnic economy of the area south of the Yangtze River. Its remote to the Central Plains, closed off by mountains and without convenient traffic facilities. The dwellers were conservative and took business as a debasing activity. Together with the natural disasters -- floods, landslides and mud-rock flows -- the productivity and culture there were far inferior to that developed on the Central Plains.
