不要开心得太早，笑到最后的人才是真正的赢家

Do not be happy too early,people who smiles to the end is the genuine winner

Does not want to be happy too early, smiles to the final person is the genuine winner

It's not until the fat woman sings.

直译：还没到胖女人唱歌的时候。
含义：女高音歌唱家（通常……胖）的歌曲是压轴节目，所以这句话的意思是还没到最后，结果还不知道。

Don't count chickens!(俚语)The one who laugh till the last laughs the best!

Those who laugh last, laugh best.
