After the origin of the mud horse Du Kang Wang, the wrench jujube tree ashore and the banzao village, many people are questioning the authenticity of the story taking place in Yanjin.

In fact, professors and experts from Xinxiang College have already demonstrated the authenticity of the story. In The village of Feng Banzao in Mazhuang Township, they made a field trip to the place where the legendary mud horse Du Kang Wang occurred, and explored the possibility of King Kang crossing the Yellow River here. Although there are many legends of the mud horse Dukang King in China, everyone agrees that the place where the story takes place must meet three conditions: one is north of Kaifeng City; the other is on the post road leading to the capital City of Kaifeng in the north; and the third is that the river should be near the ferry port with relatively narrow river water. At that time, the Yellow River in Yanjin territory of The Horse Village Ferry is now Xiaodian Town, Yichun Ferry, also known as Yanjin Ferry, Shamen Ferry and Ban ZaoDu three ferries, the northernmost ferry is Ban ZaoDu, Kang Wang is most likely to ride a horse across the river here. Because the silt of the Yellow River was too thick and the horseshoe fell into the mud and could not move, King Kang had no choice but to swim across the river. In case of crisis, it is likely that a sour date tree on the shore will be moved to save lives.
After King Kang came ashore, he walked three miles in the direction of Kaifeng and passed by the Fujun Temple, which is now the Wuliang Temple, and the Liang Temple still enshrines the Ten Halls of Yan Jun. During the rest, he dreamed that The Prince of Fujun gave him a good horse and asked him to ride a horse quickly, passing through Shi Yidian, which is now the county seat of Yanjin County, where he used to drink horses. The Chronicle of Yanjin County once recorded that there was a drinking horse terrace in the east of the city.
Go another ten miles to the southeast to the original Yangqi Street Township MaTanpu, the horse has been sweating, Kang Wang doubted, the horse suddenly turned into mud on the ground, the village got the name of Matanpu. In Ma Tan Pu Village, there is still a legend that the mud horse Du Kang Wang made a pile of dirt on this beach. The legend of MaTanpu has been included in the county-level intangible cultural heritage of Yuanyang County. Although the mud horse Du Kang Wang is only a legend, but the Song Dynasty official station ten miles a shop thirty miles a shop, Yanjin County is just on the north-south passage to Kaifeng, King Kang from the north to the capital is very likely to take this road. In addition, in recent years, Banzao Village has excavated a number of tether stones, which can also prove the authenticity of the ancient Yellow River ferry port here from one side.
In summary, the occurrence of the Mud Horse Dukang King in Yanjin does have a certain practical basis.
