an envoy to Ashina Duobi, but also ordered Li Jing to escort Ashina Duobi. Li Jing, reading between the lines and believing that Emperor Taizong's order was to attack Ashina Duobi, after joining forces with Li Shiji, launched the attack. They defeated and captured most of Ashina Duobi's remaining forces and killed his wife, Sui's Princess Yicheng. Ashina Duobi fled further, and was soon captured by the generals Li Daozong and Zhang Baoxiang (張寶相). Eastern Tujue's nobles all submitted to Tang. In recognition of Li Jing's great victory, Emperor Taizong issued a general pardon and ordered his people to feast for five days. He also created Li Jing the greater title of Duke of Dai. When Li Jing returned to the capital, however, the imperial censor Xiao Yu accused him of allowing his soldiers to plunder the Eastern Tujue treasury. Emperor Taizong rebuked Li Jing, but still increased the size of his fief and awarded him with silk. Later, regretting rebuking Li Jing, he stated to Li Jing, "People have accused you to hurt you. I realize this now. Please do not mind it." He awarded Li Jing with even more silk. Later in 630, he made Li Jing Shangshu Pushe (尚書僕射), the head of the important executive bureau of government (尚書省, Shangshu Sheng), also a chancellor post. It was said that Li Jing spoke very little when conferencing with other chancellors—then considered a virtue. A more plausible explanation is that Taizong didn't trust his high officials, especially the generals, and Li Jing was very sure about it. He deliberately tried to keep a low profile in order not to raise Taizong's suspicion. In 634, Emperor Taizong wanted to send some officials to examine the circuits in the empire, to see whether the local officials were capable, to find out whether the people were suffering, to comfort the poor, and to select capable people to serve in civil service. Li Jing recommended Wei Zheng, but Emperor Taizong, believing that he needed Wei to stay at Chang'an to examine his own faults, declined, instead sending Li Jing and 12 other officials to the circuits to examine them. Li Jing's zone was Ji'nei Circuit (畿內道, roughly modern Shaanxi). After this tour, Li Jing, giving the reason that he had a foot illness, requested to retire. Emperor Taizong agreed, but still ordered that he maintain a staff and that, once he got better,
