 However, when Emperor Taizong asked Xiao how he felt that the life of the dynasty could be extended, Xiao suggested enfeoffing the imperial princes, and Emperor Taizong agreed and began considering doing so.Around the new year 628, Xiao was again removed from his position, for reasons not stated in history, although in spring 630 he was made a de facto chancellor as imperial censor.Later that year, he accused the general Li Jing, after defeating and capturing Eastern Tujue's Jiali Khan Ashina Duobi, of allowing his soldiers to plunder Tujue's treasures, but Emperor Taizong took no actions against Li Jing, on account of Li Jing's great accomplishment.
