吴王
In 222, after Sun Quan became the King of Wu (), he promoted Gu Yong to the positions of Minister of Imperial Ancestral Ceremonies () and Prefect of the Masters of Writing () in his kingdom. He also enfeoffed Gu Yong as the Marquis of Yangsui District (). As Gu Yong went straight back to his office after his conferment ceremony, his family did not know that he had been made a marquis so they were very surprised when they found out later.
