North Suburb Burial Mound.
It's considered a taboo among the people of Chengdu Prefecture.
During the previous Great Xing Period, there was a standoff between the North and the Golden Tent Wolf Country.
The Shu region was one of the focal points of contention, with the Great Xing court establishing a series of mountain fortresses by leveraging the strategic terrains of the Yangtze River, Jialing River, Min River, and Tuojiang River basins, historically known as the "Four Carriages" and the Eastern Sichuan "Eight Pillars".
Kui Gate White Emperor City, Hechuan Fishing City, Luzhou Shenbi City, and Wanzhou Tiansheng City were among the most renowned.
Chengdu Prefecture was close to Fishing City, plus it formed a fortified line in conjunction with Yunding City and Huai'an Military City.
Alas, no fortress is completely impenetrable.
