When he arrived at Wei Prefecture, it was in the aftermaths of a major Eastern Tujue incursion earlier in the year, and the local officials were all busy conscripting labor to build the city walls, despite the fact that it was also harvest season.
Jing later successively served as deputy minister of defense (夏官侍郎, Xiaguan Shilang) and prefect of Tai Prefecture (泰州, roughly modern Taizhou, Jiangsu).
Later in the year, when she took up residence for a period at the western capital Chang'an, Jing served as the deputy official in charge of Luoyang and was known for his talent and honesty.
In spring 706, Jing was further sent out of Chang'an, which was now capital again, to serve as the prefect of Hua Prefecture (滑州, roughly modern Anyang, Henan).
Later in spring 706, with all five of the coup leaders already out of the capital, Wu Sansi and Empress Wei made accusations against them, and they were demoted to more remote prefectures—in Jing's case, to be the prefect of Lang Prefecture (朗州, roughly modern Changde, Hunan).
The five were further demoted with the provisions that they would never be allowed to return to the capital Chang'an, with Jing becoming the military advisor to the prefect of Yai Prefecture (崖州, in modern Haikou, Hainan).
Emperor Zhongzong, citing that the five had been previously awarded iron certificates that guaranteed that they would not be executed in recognition of their contribution, ordered that they be reduced to commoner rank and permanently exiled to the Lingnan region with their families—in Jing's case, to Qiong Prefecture.
