not show one’s ability but drift with the mortal world ❍ 挫其锐，解其忿，和其光，同其尘。(《老子》四章) It blunts its sharpness. It unties its tangles.It softens its light.It becomes one with the dusty world.
和光同尘he guang tong chen
conceal one’s brilliance and be as humble as dust
和光同尘hé ɡuānɡ tónɡ chén
和光：把所有的光彩混合在一起；同尘：与世俗混同在一起。比喻与世俗混同，不标新立异，不露锋芒，与世无争；也比喻随波逐流或同流合污。drift with the current, not show one’s ability but drift with the mortal world, not to distinguish oneself in sth.
