An inclusive policy for religious beliefs was adopted during the Sui and Tang dynasties (589-907), giving rise to an era of unprecedented prosperity for Taoism and Buddhism. During the Tang Dynasty, Lao Tze was canonized as an "Ancestral Sage". Taoism continued to develop and various Taoist sects coexisted, such as the Shangqing, Maoshan and Louguan sects. Meanwhile, numerous Buddhist temples were constructed, many senior Buddhist monks cultivated, the translation of Buddhist sutras was promoted, and several Buddhist sects developed, accelerating the localization process of Buddhism. The Central Plain was the major area for the spread of Taoism and Buddhism at that time, preserving a great wealth of Taoist and Buddhist remains and bearing witness to the prosperous era of the Tang Empire.
