Yang Liang
Also in 602, Yang Guang, believing that Yang Xiu would eventually create trouble for him, had Yang Su collect evidence of Yang Xiu's wastefulness and use of items that were only appropriate for emperors. Yang Su submitted the evidence to Emperor Wen, and Emperor Wen, in anger, recalled Yang Xiu to the capital. After Yang Xiu arrived at the capital, Yang Guang further manufactured evidence that Yang Xiu had cursed Emperor Wen and Yang Liang. In anger, Emperor Wen reduced Yang Xiu to commoner rank and put him under house arrest.
