Yu Jun wants to study but tradition dictates she can't because she's a girl, so she dresses as a boy and goes to school. There she meets Liang and falls in love. Liang visits her and realises she is a boy. They fall in love and he asks her father for her hand in marriage. Her father refuses and Liang, realising he cannot have Yu Jun, becomes ill and dies. Yu Jun is determined to be with her only love - what will she do to be with him again?
This story could be used to inspire pupils to design their own butterfly in an Art lesson. A display could then be created of the class' 'mariposas'.
