from Emperor Taizong. When he was then accused of being disrespectful to the emperor, Emperor Taizong laughed it off and gave him the calligraphy. In 642, when Emperor Taizong wanted to review the imperial historical records that the imperial historian Chu Suiliang was responsible for keeping, Chu rebuffed Emperor Taizong, stating that it would be irregular for an emperor to look at how an imperial historian was writing about him. Emperor Taizong then made the comment, "Do you record the bad things I do as well?" Chu responded, "It is my responsibility, and I would not dare not to record them." Liu then stated, "Even if Chu Suiliang does not record them, everyone will." Emperor Taizong agreed with both of them.

Later in 644, when Emperor Taizong, at an imperial gathering, stated to his key officials their strengths and weaknesses, he spoke, with regard to Liu: Liu Ji is firm and faithful, and he benefits the administration in what he does. However, he overly emphasizes his promises and thus overly favors his relatives and friends. Soon thereafter, he made Liu
