Laozi
In accounts where Laozi married, he was said to have had a son named Zong. They are separated when Zong is a child. Zong became a famous soldier and defeated many enemies. Laozi was teaching the Dao, and Zong learns Laozi is his father. Laozi says it is better to treat a beaten enemy with respect and that disrespect to the dead would cause his enemies to seek revenge. So Zong orders his soldiers to bury the enemy dead and hold funeral mournings. Lasting peace is then made.
