kao孟婆湯沒了
[kao mèng pó tāng méi le]
In Chinese mythology, 'Meng Po Soup' helps souls forget past lives. By saying this soup is 'gone', it metaphorically means the person can't forget something important from their past, usually implying regret or nostalgia. 'Kao' is likely expressing disappointment or frustration in informal internet slang.
