The Magic Lotus Lantern is a Chinese fairy tale from the Tang dynasty (618–907).
Against the wishes of her brother, Erlang Shen, she steals an artefact known as the lotus lantern, capable of subduing any creature man, beast, and even deity, and escapes Heaven to be with her lover.
When Chenxiang is 7 years old, however, the family is discovered by Erlang Shen, who kidnaps the child and demands the return of the lotus lantern.
As he grows into a young man, he comes under the tutelage of Sun Wukong, who crafts for him a powerful axe which he uses to take on his uncle.
Chenxiang splits the mountain in half using the axe, freeing Sanshengmu and reuniting mother and child.
