What is the origin of Guanyin Society?

According to "Chinese Sorrow Classic", Guanyin is a prince with no pure thoughts on the wheel of the Holy King, and his name is unlimited. He made a big wish: to have great compassion, cut off the suffering and troubles of all beings, and let all beings be safe. Therefore, Bao Tathagata named him Guanyin. Hua Yan Jing said: "A brave husband is at ease". Guanyin, who was introduced to China during the Three Kingdoms period, was still a mighty man. The murals of the Mogao Grottoes in Dunhuang, Gansu Province and the statues of the Southern and Northern Dynasties are all men, and Guanyin has two beautiful moustaches on his lips. Influenced by the icon of the Christian Virgin Mary holding the baby Jesus, in the18th century, Prince Guanyin, who had no pure thoughts, became "Goddess of Mercy with a Thousand Hands, Goddess of Mercy with a Son, etc." And now we see that most of the Guanyin bodhisattvas are women. So far, it has become a good project to make money and "manage", and it has indeed attracted the worship of many women who pray for their children, which has increased the income of the temple. If you tell those who worship them that this is a prince or a man, I am afraid that the old ladies who worship Buddha will unite to call you a "fool". The origin of Guanyin Society is the same.
