吃一堑长一智 Be bought a lesson ; No pain no gain ; Sbagliando s'impara ; A fall into the pit

不长一智 No pain no gain ; Be wise

经一事长一智 A lesson ; we learn from our mistakes ; it's easy to wise after the event

近一事长一智 Almost a wiser ; Nearly one-A-chi ; Recent issue of a lesson

不经一事不长一智 wisdom comes from experience ; Aus Schaden wird man klug

吃一椠长一智 Aus Schaden wird man klug
