When Gong Sun Yang led his troop to shut down all the mines which had been providing Hao Tao with resources, another uncle of Gong Sun Xun, named Gong Sun Lang, led a formidable army and marched to Yao Mountain territory.
Same as Gong Sun Yang, Gong Sun Lang was also a lascivious alcoholic, a typical one among all ungifted members of the Gong Sun Family. Gong Sun Yang was discharged from his position two months before the abdication ceremony for embezzling public funds. But, Gong Sun Lang was nearly cast out of the family twenty years ago for committing adultery with a mistress of the family leader.
Before the ceremony, he had no job or income. He lived a faineant life in the Gong Sun Family for twenty years. Gong Sun Xun basically learned about how to be a loser from him.
