PS: In Taiwan, on the island of Lan Yu, the local dialect has no proper name for butterfly. Instead, they call it Babanalid u (i.e., Soul of a Demon). Hopefully, this enlightens those who are wondering why the Chinese film title "Butterfly" gets translated differently. Actually, in some Chinese folklores, stories, films or beliefs, those who die are depicted to have transformed into butterflies.
