Introduction to Mahao Cliff Tomb: It is located on the east bank of the overflow river between Lingyun and Wuyou Mountains. Mahao is its place name. Because this type of tomb was popular from the Eastern Han Dynasty to the Northern and Southern Dynasties more than 1,800 years ago, it is called the Cliff Tomb of the Eastern Han Dynasty. In the early years, Mahaoya Tomb was known as "the crown of all tombs in Nan'an" because of its large scale and exquisite portrait carvings.
