Wangchuan was born in the Wangchuan River.
The Emperor of Heaven said that no living thing had ever been born in the Wangchuan River. Since he was born there, he should be called Wangchuan.
Wangchuan's voice is very nice, and he always likes to ask me a question, asking who he is...
Wangchuan forgot who he was, maybe he never knew who he was...
