Set in 11th-century Song dynasty, the play tells the story of a carp spirit seducing poor student Zhang Zhen by metamorphosing into a woman, who closely resembles Zhang Zhen's lover Jin Mudan.
[1] In the Yue opera tradition, the play is known as Zhuiyu (追魚, literally "Chasing the Fish").
In this version, Jin Mudan is a material girl while the carp spirit is kind.
This version ends with Zhang Zhen's marriage to Carp Spirit instead of Jin Mudan.
