A very clever effect with built in laughs and amazement!

You show the backs of four Chinese playing cards, saying that these are the four Queens. A spectator freely names a Queen. You display the cards and one has turned over, which you claim is the chosen Queen. But it has Chinese characters printed on it!  Of course, what do you expect they're Chinese cards!

Finally, you turn over the cards to show that this is the only one with a "translation" on its back... the correct Queen!

Unusual props, great story and a stunning finish!  The spectator can choose any queen they wish.
