While Yang Yong was crown prince, it was clear that Emperor Wen and Empress Dugu favored his younger brother, their second son Yang Guang the Prince of Jin. In summer 581, Yang Yong's chief of staff Lu Ben (), trying to exploit this situation to gain Yang Yong's favor, tried to get Yang Yong involved in his plot to, jointly with several other officials, take over power from Emperor Wen's favored officials Gao Jiong and Su Wei. The plot was discovered, and Lu Ben and his associates were deposed, but Yang Yong was not punished.
