- 我说以前是不熟,不懂,英雄无用武之地。
they have been like "a hero with no place to display his prowess ". - 而当市场火爆之时,“跑单小姐”更是英雄无用武之地?
When market unpopular at the time, "Run-Miss" is a hero without a battlefield? - 英雄无用武之地,就是说,你的一套大道理,群众不赏识。
By "a hero with no place to display his prowess", we mean that your collection of great truths is not appreciated by the masses.
