Besides worshipping Buddhism and Empress Wu, the Longmen Grottoes also reflect political, economic, and cultural lives in ancient China. The sculptures describe the people in the fields of arts, architecture, calligraphy, music, dressing and medicine.
Although much of the site has been well preserved, during its long history, some parts were damaged by natural erosion and vandalism. Crevices in the rock bases caused some caves to collapse. Saline sediments resulting from acid rain, train and automobile vibrations and natural disasters have also affected the site.
