Ten percent of Tayuan Temple's 20,000 Buddhism sutras (canonical scriptures) were written in between the Song Dynasty to the Qianlong Reigh of the Qing Dynasty.
There are 20 layers of wooden rotating wheels in the Cangjing Mansion, each of which is placed with over 20,000 Buddhism sutras in Chinese, Mongolian and Tibetan characters. Among them, there are over 2,000 complete and widely-read sutras that were written between the Song Dynasty to the Qianlong Reigh of the Qing Dynasty. In Buddhism, sutras, also known as suttas, are canonical scriptures, many of which are regarded as records of the oral teachings of Gautama Buddha.
