Outwit the birth class is the most important and wonderful story of Water Margin, which happened in Huangnigang, Yuncheng.

Huangnigang in the novel is not far from Dongxi Village where Classical is located. Ten miles east of Huangnigang is the happy village where Yum is located. According to the geographical location, people think that Huangnigang is Huangnigang Town in the southeast of Yuncheng County. Although the terrain here is flat now, it was a raised mound decades ago. In the 1970s, a stone tablet from the Wanli period of the Ming Dynasty was unearthed here.

The tablet says: "During the reign of Xiangkao Chongning in the Northern Song Dynasty, there were 800 miles of water around Liangshan, and the pile was 60 miles away from Liangshan, which was the south bank of Liangshan Lake and was called Huangnigang in ancient times." It is also mentioned in the monument that the terrain here is high, and fishermen rest and dry fish on this mountain.

Some people may ask, in the Northern Song Dynasty, Water Margin reached Juye County in the south, Yuncheng County in the west and Wenshang County in the east. That place called Huang Duiji should be the water surface of the Water Margin. How can it be a post?

Huangduiji, this place, really belongs to the water surface of the Northern Song Dynasty. However, Water Margin often uses the situation of Yuan Dynasty or Ming Dynasty to write the Northern Song Dynasty. For example, it is said that Gao Qiu was the float of the Xuanwu Army in Kaifeng. There was no Xuanwu Army in the Northern Song Dynasty, but there was Xuanwu Wei in the Ming Dynasty, just west of Kaifeng. Of course, there was also the Xuanwu Army in the Tang Dynasty. Zhu Wen, who betrayed Huang Chao and took refuge in the Tang Dynasty, was the envoy of Xuanwu Army. He established the Liang regime in Kaifeng and built a palace in the official residence of the former envoy.

Huangduiji this place should be the same. At the end of the Northern Song Dynasty, the Yellow River moved south, and the water margin in Liangshan Park gradually narrowed and moved north because of the loss of water source, so the Yellow River was located on the southwest bank of the remaining water in Liangshan Park.

Some people say that "Water Margin" wrote that Yang Zhi took people to Huangnigang, and there were mountains and ridges, but there were no mountains in Huangduiji. We said that the novel was written about people from these backgrounds, and that was before they came to Huangnigang. When we arrived at Huangnigang, it was clearly written on the water margin, and it was a dirt hill.
