 In fall 616, while Emperor Yang was inquiring about the status of agrarian rebellions (by this point, most of Sui territory was in fact engulfed in agrarian rebellions), Yuwen, in order to placate him, informed him that the rebellions had largely been suppressed.Su, however, truthfully informed Emperor Yang that the rebellions were causing major problems for Sui rule.Emperor Yang, not happy about the news, soon considered putting Su to death, but eventually only reduced Su to commoner rank.
