One of the three main Guanyin Festivals.
Guanyin is one of the most revered Bodhisattvas in Yunnan and her (or sometimes his) statue can be found everywhere.
In China, Guanyin is not only revered as a Buddhist Bodhisattva, but is also a Daoist immortal, making Guanyin worship almost universal.
The Nanzhao Empire in the Dali region made Buddhism and particularly Guanyin worship state religion and even today the Bai consider Guanyin their protector spirit. Before the Song dynasty Guanyin was considered a male god and in early Bai myths Guanyin often appears as an old monk from India.
