A gentleman will not stand under a dangerous wall
A son of rich wealth will not sit down in the hall
"Jingxi" by Du Xunhe of the Tang Dynasty
The rocks in Jingxi River are dangerous and people are cautious, and they never hear of people capsizing.
But it is a place where there are no rocks in the level flow, and there are always reports of people sinking.
Zhuangzi’s Quotations
Careful can catch cicadas of thousands of years; carefulness can sail a ship of ten thousand years
