Zhuangzi's original words: "Big knowledge is idle, small knowledge is short, big talk is hot, and small inflammation is obvious.".

It means that the smartest people always show an open-minded attitude; Small and talented people always haggle over trifles. The speech that conforms to the avenue is like a prairie fire, which is beautiful, grand and convincing; Those clever remarks are trivial and meaningless.

PS: Idle and broad-minded; Sometimes it's like observing carefully.
