Jingbo Lake has a long-standing history. Long, long ago, the Manchus lived and worked and multiplied in this area. According to historical records: In the 15th year of Emperor Zhouwu (1666 B.C ) and the 9th year of Emperor Zhoucheng (1654 B.C ) there used to be the ceremony of paying tribute by Sushen nationality to the emperor. Yilou nationality in the Western Han Dynasty and the Jin Dynasty, Wuji nationality in the Northern Wei Dynasty, Mohe nationality in the Sui and Tang Dynasties, Nuzhen nationality in the Song, Yuan, Ming and Qing Dynasties. All of them were the descendants or branch nationalities of Sushen nationality. This nationality set up a country which was named Dazhenguo afterwards, which moved the capital to Huhan City, in 740 A.D.. The site of city was on the highland, southwest of Sijitong near the Tingbo Lake. (It was called Huhan Sea at that time ). Nowadays the ruins of the city can still be seen there.
After China was liberated, the archaeologists have found four pottery hogs buried in red earth of Yingge Hill, on the south of Jingbo Lake. It was people of Sushen nationality who made these precious works of art. In every corner of the Jingbo Lake region, from the ruins of the ancient city, which used to be called Bohaidongjing City, to the Ning Gu Pagoda, the archaeologists have left their footprints.
The mystery of Jingbo Lake has been gradually brought to light, but most of them are still waiting for the geographers and archaeologists to explore.
