“Big Fish & Begonia” 大鱼海棠
lost in translation lah :(

according to wiki: the main actress is a fairy in charge of begonia (掌管海棠花)

the main actor, he change into "鯤" a legendary big marine creature, its body is more than several thousand chinese miles long (鯤之大・不知其幾千里也).

"big fish" is a good enough name for such marine creature.

anyway, it's an anime for children, need to have a simple, easy to comprehend name, for both the local &amp; foreign kids.

have fun :)
