Zheng Banqiao's couplet "The sea accommodates hundreds of rivers, and tolerance is great; standing on a wall of thousands of feet, without desire is strong." Its meaning is: the width of the sea can accommodate many rivers; it is a metaphor that a person's broad mind can tolerate everything; or It is a metaphor for a company's vast resources. The reason why the Qianren Cliff can stand tall is because it has no worldly desires; it is a metaphor that only when people have no worldly desires can they achieve the state of righteousness (rigor).
