看你干的蠢事
[kàn nĭ gān de chŭn shì]
Translated literally as 'Look at the silly things you have done (看你干的蠢事)', this expresses a light-hearted rebuke or reflection on past actions that were nonsensical, foolish or regretful. It may imply self-critique or playful teasing in recalling embarrassing mistakes one has made.
