「反者道之动；弱者道之用」
“Reversal is the movement of the Dao; softness is how the Dao is used”
—— 道德经反者道之动；弱者道之用：道以返回为动，以柔弱为用——盛极而返的提醒。可与柔弱胜刚并读。今日：高峰期，预留「反」的空间，比硬撑更合道。
Reversal is the Way’s movement; weakness is the Way’s use—motion as return, use as soft. Pair with soft overcoming hard. Today: at a peak, leave room for reversal; it fits the Way better than bracing.
