The birthday of Guanyin Bodhisattva is February 19 of the lunar calendar. The day when Guanyin Bodhisattva became a Taoist is June 19 of the lunar calendar. Guanyin Bodhisattva becomes a monk on September 19 of the lunar calendar.
Buddhism believes that Guanyin Bodhisattva is a kind and compassionate Bodhisattva. As long as the victims recite his name, "Bodhisattva immediately observes his voice" and goes to save liberation, it is named. Because of the taboo of Emperor Taizong Li Shimin in the Tang Dynasty, the word "world" was briefly called "Guanyin".
As for Guanyin Bodhisattva, the name of this Bodhisattva is listed in volumes 82 and 100 of chengyouguangdingyi Sutra, Vimalakirti Sutra, guangzanprajna Sutra, dabaoji Sutra, but there are no stories such as origin. In the Dharma Sutra, there is a product detailing the Bodhisattva's benefit to life in the Saha world.
In addition, Volume III of the compassion Sutra, the book of Bodhisattvas, describes that Amitabha Buddha, the eldest son of Wang Wuzheng in his past life, became a monk in front of the treasure Buddha and vowed to recite. If all sentient beings suffer from all kinds of distress and terror, if he can remember me and recite my name, he will be relieved of all kinds of pain and trouble. The treasure Buddha recorded and named Guanyin for him.
Guanyin belief has a far-reaching influence in China, resulting in various folk legends about Guanyin Bodhisattva, such as the widely spread saying that Guanyin is the third princess Miaoshan of Miaozhuang king of Xinglin country. This legend of female Guanyin can be seen in the Song Dynasty Zhu Bian's "old news of Qu Yi".
Later, Guan Daosheng's biography of Guanyin Bodhisattva in the late Song Dynasty and early Yuan Dynasty became a complete biography. Taking this as the blueprint, a large number of Guanyin story books such as Xiangshan Baojuan, the complete biography of Guanyin in the South China Sea and Guanyin's enlightenment have appeared one after another.
