Gongsun Yuan
In 233, when Sun Quan wanted to form an alliance with the Liaodong warlord Gongsun Yuan against Wei, he sent He Da as his representative to meet Gongsun Yuan. However, Gongsun Yuan betrayed him and executed He Da. He Da's son, He Zhi (賀質), served as a Tiger's Teeth General (虎牙將軍) in Wu.
