Introduced the conviction and sentencing policy of "three pardons and three pardons" stipulated in the "Zhou Li, Autumn Officials, and Si Ci". San You refers to the leniency given to three situations where a crime is committed due to ignorance of the law, negligence, or forgetting regulations. Three pardons refer to the granting of pardons for crimes committed by individuals under the age of 7, over the age of 80, and with intellectual disabilities. This is the principle of criminal law in the Western Zhou Dynasty, reflecting the rulers' cautious punishment thinking.
