How it's used
This idiom is primarily reserved for formal or academic contexts, often used to praise the depth of traditional arts, philosophies, or complex systems. While it can be applied to everyday topics like food or language, doing so often carries a slightly playful or exaggerated tone to emphasize how surprisingly complex the subject actually is. It functions as a high-level compliment for someone's expertise or the richness of a cultural practice.
Examples
Traditional Chinese medicine is vast and profound; you cannot master it in just a few years.

Common mistake
Learners often mistakenly use this to describe a person who is smart or knowledgeable, but it should only be used to describe the subject matter or field of study itself, not the individual.
