Having seen the world or experienced the great ups and downs of life; meaning that after witnessing something vast or grand, ordinary things no longer seem impressive. Often refers to having broad knowledge or being sophisticated through experience. From a poem by [[元稹|元稹|yuan2 zhen3]] based on [[孟子|孟子|meng4 zi3]].

Having seen the vast ocean, other water seems insignificant; used to describe a person so experienced or well-traveled that ordinary things seem unremarkable. From a Tang dynasty poem by [[元稹|元稹|yuan2 zhen3]]

Literally translated as "no water is wide enough after one has seen the great ocean, and no clouds compare to those over Mount Wu." This poetic expression describes having seen the best of something or having experienced a deep love, such that nothing else can ever compare or satisfy.
