The word soufflé comes from the French past participle souffler, which means "swelling", and is used to describe the phenomenon that the egg sauce is mixed with protein. Chinese translation into Chinese means "Li Shu" or "Shu Fu Lei", because the original name of this dessert is "souffle", which is French, so Chinese translation into "Li Shu" has no special meaning.

Supplementary explanation:

There is an explanation for this word: this air-filled dessert is mainly made of egg white, so you can say that the original meaning of this word is the name of the dessert.
