more than a hero ? – 識英雄重英雄

one of my favorite old Chinese quotes,  meaning,

“those who can tell  which person is a hero  are more than a hero”

Put it in another way :  “only heroes know who are heroes”
My extension :  “only smart people know who are smart”

識  =  know,       英雄 =  hero,       重 =  more than
