Wendi
Yang Yong was recorded as being lenient, kind, and honest in his nature, making few pretenses, but he favored luxuries, much to the chagrin of Emperor Wen, who favored frugality. Once, when Yang Yong made a highly decorated set of armor, Emperor Wen rebuked him, sending him an undecorated sword that Emperor Wen himself employed, as well as a box of miso, to remind him that prior to becoming crown prince, he had to settle for common items such as those. The relationship between Emperor Wen and Yang Yong was further strained when, at Dongzhi, Yang Yong openly welcomed officials to his palace, which Emperor Wen interpreted as Yang Yong's receiving submission from those officials—an act that Emperor Wen considered inappropriate as Yang Yong, while crown prince, was still an imperial subject.
