Thousand Autumns is an example of a story where a "good" character is not defined by strength or intelligence. Although Shen Qiao is indeed a powerful character, it's not limited to physical ability. He is morally just and his greatest strength is that he stays true to himself and nothing can tempt him from going astray. I love how the other main character, Yan Wushi, is Shen Qiao's foil yet they respect each other's opinions. Both characters are very strong (mentally and physically) and won't hesitate to achieve their goals.
