As the dictionary says, knights-errant are just, brave and kind, eschew violence, and help those in need. "Since ancient times, knights-errant have been courteous, brave defenders of the right." The Chinese have long held knights-errant in high esteem. Even today, the term provides ample fodder for the imagination.
現代武俠小說中的大俠面貌或有不同，但正如李慕白，俠客有志一同的，都是「義之所在，雖死不辭」，如辭典說的，大俠是好義勇為，除暴安良，濟弱扶傾，「古來俠者所以為俠，就是以明是非、知禮義、重骨氣著稱。」
