In February of the lunar calendar, Emperor Wudi of the Eastern Jin Dynasty was ordered to lead an army to conquer the Southern Yan State. On the way, he was surprised to find that the mountain was naturally dangerous and easy to defend but difficult to attack. There is the Wenhe River in the north, and the river is swift, forming a natural barrier, just like a river to protect the city. So he chose to camp at the foot of the mountain, established a base camp, and stationed troops in surrounding villages more than ten miles below the mountain.
