詞條：既有今日，何必當初
ji yǒu jīnri,hebi dāngchū
[if there must be today,then why should there have been other days;if I had known it would come to this,Iwould have acted differently;if it has to be like this now,it's a pity it was even like that in the beginning] 既然有今日的如此結果,何必在當初那麼做。用以感慨現今的不如意,而深悔過去的錯誤
寶玉在身後面歎道:「既有今日,何必當初。」－－《紅樓夢》
