According to legend, a long time ago, the Yellow River flooded. Shun used Da Yu, the son of Gun, to inherit his father's business and control floods. Yu's method of controlling water is dredging. The Jade Emperor ordered his youngest daughter to descend to earth, became a native girl, and married Dayu to help him control water.

Dayu dredged the flood of the Yellow River to the northwest of Hejin, Shanxi Province, and the northeast of Hancheng, Shaanxi Province, across the banks of the Yellow River, shaped like a cliff mouth of a mountain gate, and finally diverted the flood. This mouth is called Yumen.

Carp living in the Yellow River was rushed out of Yumen and suddenly fell from a waterfall more than ten feet deep. The carp could not go upstream and returned to their hometown, so they protested to the Dayu couple. Tushan said with a smile, "I'll invite the Jade Emperor to play. Those who can leap into the gap will immediately become dragons, soaring into the sky, and their foreheads and cheekbones will be broken. They can only blame themselves for being born a mediocre person, so stop it. "

From then on, in the late spring, countless golden carp went upstream along the Yellow River, gathered in Yumen and struggled to jump. Those who occasionally jump over, they become black dragons and take off for nine days. The Yumen of Longteng is called Longmen, a Yuelongmen, which is worth a hundred times.
