Introduction to Wu Ying Jiugong Bagua Array: Wu Ying is built with stone materials, which is in sharp contrast to the wooden structure of Cao Ying. Wu Camp mainly includes Zhou Yu’s Dianjiang Platform, Seven Star Altar, Water Village, Nine Palaces and Bagua Array and other major landscapes. The "Zhuge Liang borrows the east wind" in the Seven Star Altar and the "Nine Palaces and Bagua Formation" outside Wuyingyuan Gate are good places to appreciate Zhuge Liang's magical calculations.
