Yuan had an outspoken personality, and after being put into an advisorial post, he started submitting suggestions to Emperor Xianzong. In particular, because the officials Wang Shuwen and Wang Pi, who dominated the court of Emperor Xianzong's father Emperor Shunzong — who had previously served as Emperor Shunzong's staff members while Emperor Shunzong was crown prince — were at that time denounced as frivolous and power-hungry, Yuan submitted an essay detailing what he saw as qualifications that the crown prince's and other imperial princes' staff members should have, and Emperor Xianzong was impressed upon reading it. Yuan further submitted proposals involving the defense of the northwestern borders with Tufan and Huigu. Emperor Xianzong, in response, summoned him and requested opinions on strategies to take there. As a result, though, the ruling officials at the time were jealous of Yuan, and they had him sent out of the capital Chang'an to serve as the sheriff of Henan County (), one of the two counties making up the eastern capital Luoyang. Yuan subsequently left governmental service for some time while observing a mourning period after his mother's death. Once the mourning period was over, he was recalled to governmental service, to serve as "Jiancha Yushi" (), a mid-level imperial censor.
