The grottoes are scattered among numerous pine and cypress trees that grow on Tianlong Mountain and were were built during the Eastern Wei Dynasty (AD 534-550), the Sui Dynasty (AD 581-618), and the Tang Dynasty.
There are 1,500 statues and figures created during the Tang Dynasty period, when the emperors opened their minds to Buddhism.
A shining example of Buddhist art during this time is the Bodhisattva Maitreya sculpture that has harmonious proportion and shows off an amiable and lenient smile.
The people from the Tang Dynasty worshipped the Bodhisattva Maitreya, regarding him as the symbol of a bright future.
The Kwan-yin sculpture is equally impressive with her charming countenance.
