Hejiaban, also known as He Xiangu's hometown, Zhengning Luochuan is Zhang's hometown, and there is a Guo ancient tomb group in the rolling hills on the western slope of Zhengning, which is supported by many poems and songs in Ming and Qing Dynasties, and there is a hill named Eight Immortals Knot in Zhengning. All these seem to prove that the Eight Immortals have an inseparable relationship with the yellow land of Longdong, and their views only exist in Xi 'an (ancient Chang 'an) and have their historical origins. The story is always original, and it can't be groundless.
