Why is Fahai afraid of Guanyin?

The two are not on the same level. In the movie "The Legend of the White Snake", Guanyin's position is much higher than that of Fahai, who was only a mortal at this time, so Fahai is very afraid of Guanyin. Legend of the White Snake is one of the four great folk love legends in China, which was created by China folk collectives. Originated from the Luoyang serpent incident in Tang Dynasty, it was initially formed in Feng Menglong's Warning Story in Ming Dynasty. It is mature and popular in Qing Dynasty, and it is a model of China folk collective creation.
