In geographical concepts, "eight hundred li" is often a figurative term, emphasizing the vastness of the territory. In a single imperial edict issued by Emperor Xianzong Zhu Jianshen of the Ming Dynasty, the majestic Wudang Mountain was consolidated into four boundary stones - reaching the strange peak of Guanzi Mountain in the east, locking the perilous pass of Yaicanzhai in the west, guarding the ancient path of Maicangao in the south, and protecting the White Temple and the misty waves in the north.

Five hundred years of wind and frost have etched these boundary markers engraved with "imperial edicts", using stone bones as brushes, interpreting the profound meaning of the Ming court's "using mountains as screens and governing the territory with roads" among the peaks in the northwest of Hubei Province. At the foot of Guanzi Mountain, the remnants of the boundary marker pass of Baiyangping in Danjiangkou City still exist. The "Junfang Boundary" of Tielu Gou divides Junzhou and Fangzhou. Beside the ancient Bai Miao 'er Path, inscriptions on steles engage in a dialogue with the waves of the South-to-North Water Diversion Project across time and space. The "Yahu Rock" in Maota Township, Maojian District, Shiyan City, has finally solved the mystery of the western boundary of the 800-li Wudang Mountain due to the local dialect pronunciation and the remains of the fort wall.

The complete territory of the "Eight Hundred Li Wudang" in the Ming Dynasty was precisely defined, making Wudang Mountain truly a "visible scenic spot and tangible heritage". Today, the boundaries of the 800-li Wudang have long transcended geographical boundaries, transforming into a totem engraved by Chinese civilization in the universe, and also an eternal echo of the cultural heritage of mountains and rivers over thousands of years.
