During the dry years of the Five Dynasties, Chongqing Pass was taken by the Khitan. Xue pointed out: "Chongqing Pass is surrounded by the sea on three sides and the land on the north. From Guanbei, Chongqing to Niukou, eight guards were placed in the old place, and soldiers were recruited to guard them, so the Khitan dared not enter lightly. And Li, the king of Jin, took Youzhou, making Zhou Dewei an envoy, relying on virtue and courage, and not trimming the border, so he lost the risk of Chongqing Pass. Qidan brushed between Ying and Ping, making a big noise. " In the late Tang Dynasty and the late Qing Dynasty, Zhao Dejun was guarding Lulong, and Shi Jingtang rebelled in Taiyuan, asking Qidan for help. Ye Ludeguang agreed, and his mother said, "If Lu Long's army goes north to Chongqing and needs to be brought back urgently, Taiyuan can't be saved."

It is said that Qin Shihuang let immortals live here. " The description of Qinhuangdao in Linyi County Records in Guangxu four years is numerous and detailed: "Wangqin Island, twenty-five miles southwest of the city, turns from east to west, inserts into the sea, and presses the water horizontally.
