How it's used

This is a formal idiom often used in written Cantonese or serious speech to describe a total loss of effort or resources. It carries a sense of finality and regret, as if the outcome is now beyond recovery. While it is understood in spoken contexts, it sounds quite literary compared to everyday expressions like 嘥晒.
