Why do people in Taoist temples force A Bing's mother to death?

Because A Bing's father is a Taoist priest, A Bing is the illegitimate child of his father and a woman, and the Taoist priest is also a monk, there is no love in the world of mortals. A Bing's mother must be sacrificed in order to maintain the reputation of Taoist priests. A Bing's father also has high attainments in temperament. He is known as the "iron hand pipa". As the saying goes, like a tiger, like a son, A Bing is also very famous in the music industry, and he wrote "Two Springs Reflecting the Moon".
