封刀不再战收心不再浪
[fēng dāo bù zài zhàn shōu xīn bù zài làng]
'Put Away the Knife and No Longer Fight; Calm Down the Heart and Be Serious.' 'Putting away the knife' and stopping the fighting express ending conflict and aggression; while calming down the wandering heart indicates giving up the restless past to embrace a peaceful and tranquil future, demonstrating maturity.
