Tibetans of Jiuzhaigou believe in the Benbo-Sec Religion which was introduced to Aba Prefecture where Jiuzhaigon is located, from Tibet in the 2nd century B. C. It was integrated with primitive local wizardry into the Benbo-Sec and became dominant in the 6th century. In the 7th century, the Tibetan Buddhism was introduced, and won in Furious conflicts against the Benbo. Although Buddhism became prevalent, the Benbo survives and develops into a special sec of Tietan Buddhism, due to its unique religious and culture features. Even today, there are over 60 Benbo monasteries and temples in Aba Tibetan-Qiang Nationality Autonomous Prefecture.
