I perfre you is fish because it is fish so play fish.
Amendment: I prefer if you were fish then you should know how to play the part of a fish. 我寧願你好像似魚兒一樣子,當然你應對於扮演魚兒的角色易如反掌。
An attempt to answer only from the (app.) by error and correction:-:-eg:-
I refer you a fish because it lies to me !(because it is fish that lies to me.)
=Don't give the lie to me like a lying fish
=I refer you to a kind of fish
=shell fish; sea fish; an odd fish
=a person who is crazy or strange or lying;
so I try not to believe you for your information.
