The Ninth Level

Across the Taihang Mountains are Jingxing County in Hebei and Pingding County in Shanxi. Jingxing is one of the eight Jingxing Mountains in Taihang Mountains. When Chang'an was the capital, it was a key place to control the southward advance of the north, especially to defend Jinyang (Taiyuan). After Beijing became the capital, it became a key route to defend the capital area of ​​Zhili, forming a pincer attack with Guguan, one of the four western passes of Beijing. This is Niangzi Pass, named after Li Shimin’s sister Princess Pingyang who garrisoned there with the women’s army. Also because of the princess’s status, it is called the Ninth Pass in the World.
