顧雍
On one occasion, one of Sun Quan's nieces married a younger maternal relative of Gu Yong. Gu Yong, along with his sons and grandson Gu Tan, attended the wedding. At the time, Gu Tan held an important position as Master of Writing in the Selection Bureau (選曹尚書; the equivalent of a present-day human resources director) of the government. During the celebrations, he became drunk and started dancing wildly in an unrestrained manner in front of his grandfather, Sun Quan and the other guests. Gu Yong felt extremely embarrassed and upset with his grandson's behaviour but he did not say anything.
