Introduction to the original boundary remains: The original boundary of Qin Shihuang’s Mausoleum was much taller than the existing one. The Western Han Dynasty people said that the length of the base of the mausoleum can be equivalent to 2087.65 meters today. Due to wind, rain, and man-made destruction over the past two thousand years, only 1,390 meters in circumference remain. This is the boundary of the original land.
