What does the story of Guanyin tell?

Bodhisattva was originally a fairy girl in the sky, and her name was Tzu Hang Da Shi. One day, Master Cihang talked with the Buddhas and watched the sound of the world by the lotus pond in heaven. They see that there are many suffering beings in the world, and at the same time, they see that there are many ignorant people who are greedy for sex, oppress the people and bully the weak and fear the hard. Master Cihang was very impressed! And said: If this continues, how can the world get rid of suffering? At this time, a snakehead stole the classics of Master Cihang, was reprimanded by Master Cihang, and was exiled to the world. On the land of China, there is a country called Guo, which is honest and loves people. The country is governed in an orderly manner and the people live and work in peace and contentment. Ms. Wang's name is Miao Baoying, and she is from Miao Zhuang Village, Nanhe County. Queen Wang and Miao are very loving. The empress gave birth to two daughters, Miao Yuan and Wang. King Miao Zhuang hoped that the queen would give birth to a dragon son for him. However, Empress Xi was pregnant for 18 months and failed to give birth. King Miao Zhuang and the old lady are very anxious! Master Cihang came to the Buddha and asked him to come down to earth to transform all beings.
