Buddhism was derived from the 6th to 5th century B.C. It was introduced to China in the Eastern Han Dynasty and reached its peak in the Tang Dynasty which was the Buddhist center of the oriental world. During that time, there were a great number of Buddhists coming from the neighboring countries to study Buddhist doctrines in the Tang Dynasty. Buddhism was introduced into China as a totally different kind of culture and gradually became the core of Chinese culture. It was originally a kind of aristocratic belief popularized in the upper class of the society and was spreading in the general civilian society as well as competed with Taoism developed in the local China on equal terms.

They recorded the relationship between Buddhism and the country, different kinds of Buddhist activities and rituals occurred in the late Tang Dynasty and social functions of the temples.
