華山
In the tale "Lotus Lantern" ("Bao Lian Deng"), Erlang had a sister known as the Holy Mother of Mount Hua ("Hua Shan"). She married a mortal man, Liu Yanchang, who was a scholar. Together, they had a son by the name of Chen Xiang. She was admonished by Erlang for this unlawful human-deity union and imprisoned under Mount Hua. When Chen Xiang came of age, he split the mountain with an axe to free his mother, but not before facing people who repeatedly tried to undermine his mission, most notably his own uncle Erlang.
