The story tells that the military commander, Zhao Shuo, the son of his jealous grandson, killed more than 300 families with the help of the State of Jin, leaving only orphans to be rescued. Tu'an Gu ordered that all infants aged from one month to half a year should be killed to avoid future troubles. And the old minister gongsun staged a trick of "stealing the day", and successfully saved Zhao's last drop of blood at the expense of gongsunhe's son. Twenty years later, when the orphan Wu Zhao grew up, Cheng Ying drew a picture to tell his country that he hated his family and finally got revenge. The work describes the contradiction between loyalty and evil, exposes the brutal nature of power rape, and praises the noble quality of upholding justice and sacrificing oneself for others, which is tragic and touching.
