Early in the "Changqing" era (821-824) of Emperor Muzong, Jia Su and Bai Juyi were put in charge of grading a special imperial examination for those with strategies, and it was said that the popular opinion at the time was that Jia and Bai were fair graders. He was soon made "Kubu Langzhong" (), a supervisory official at the ministry of defense (兵部, "Bingbu"), and continued to be in charge of drafting edicts. It was said that Jia was an excellent writer, and was intelligent and decisive. However, he was also said that he was harsh and impatient, and he often insulted his colleagues. The senior advisory official Li Bo () disliked Jia and reported this to the chancellors, but because Li Fengji and Dou Yizhi favored Jia's talents, Jia was not demoted.
