Novels, as a kind of art, often distort some historical facts intentionally or unintentionally. Here is to do justice to the couple Wu Da Lang and Pan Jinlian of "Water Margin" and "Jin Ping Mei".

Wudalang was called a "three-inch nail" and Pan Jinlian was portrayed as a slut. In fact, Wudalang was more than 1.70 meters tall, while Jinlian was a good wife and mother.

In the Northern Song Dynasty, Wu Dailang, Clan Jinlian are the neighboring Kong Songzhuang and Jinjinzhuang people in Qinghe County, Hebei Province. Wu Dalang real name Wu Zhi, the world respectfully called "Wu Dalang", is the character of talent and appearance of the poor family showman, had been successful in the examination, by the Song Huizong Qingdao as Yanggu county magistrate, for the official integrity. Clan Jinlian, on the other hand, was the daughter of Clan Zhizhu, a state official in Beizhou at that time. She married Wu Zhi and became a virtuous wife, had four sons, and grew old together.

Three elderly people recalled that in 1946, people in Kong Songzhuang were so poor that some people dug up the ancestral graves of the two big surnames of Tian and Wu, trying to get some gold and silver treasures. Wudalang's grave is tall, with a hammer and steel rod before uncovering the brick barriers, but there is only a nanmu hanging coffin and two bones. From the bones of Wu Dailang, he was at least 1 meter 70 or more.
