骑驴看唱本 qílǘkànchàngběn wait and see
(idiom) we will see what happens; wait and see who is right. This is a two-part allegorical saying based on the pun that both riding a donkey and reading a script involve the words [[走|走|zou3]] and [[瞧|瞧|qiao2]], implying the final outcome depends on how things develop.
