Weizi of Song
Weizi also spelled Wei Tsze, was the first ruler of Song. He was the subject of Chapter 18 of the Analects of Confucius.
Weizi was the eldest son of Di Yi. He was also a half-brother of the last Shang king, Di Xin. Di Xin gave himself over to drinking, women and abandoned morals. Weizi tried to persuade him not to do, but Di Xin ignored. Subsequently, Weizi resigned and withdrew from the court.
When Zhou dynasty conquered the Shang kingdom, Weizi submitted and presented the ritual utensils to King Wu of Zhou. He was pardoned by King Wu.
After Rebellion of the Three Guards was put down, Weizi was enfeoffed as Duke of Song and granted land at Shangqiu, where the capital of the new State of Song was built. After his death, he was succeeded by his younger brother Weizhong.
Weizi was honored by Confucius as "one of the three men of virtue" of the Shang, together with Jizi and Bigan.
