Demoted to: first-class general. Later, when the Jinyi Guards were ordered to confiscate Jia's house, Jia She, as one of the main culprits, was dismissed from his post and sent to the platform to atone for his crimes on the charge of "trafficating as a foreign official, bullying the weak based on his power, betraying my kindness, and showing disloyalty to his ancestors."
Jia Zheng was fond of reading since he was a child, and originally wanted to take the imperial examination. Unexpectedly, when Daishan passed away, he left a copy. The emperor, out of sympathy for his ancestors, gave Jia Zheng an additional title of principal, and he was promoted. A foreigner from the Ministry of Industry. During his tenure as an academician, Jia Zheng "acted impartially and was convinced of all children who were born". Therefore, after returning to Beijing, he was recommended by Governor Wu, and the emperor promoted him to the position of Doctor of the Ministry of Industry. After the death of Yuanchun and Wang Ziteng, the Ministry of Industry ranked Jia Zheng first. The emperor thought that Jia Zheng was diligent, frugal and prudent, so he released the Jiangxi grain road and took office the day after Baoyu's wedding. This business trip lasted for nearly a year. At the beginning of the first month of the following year, he was sent back to Beijing on the charge of "being ignorant of official governance and being deceived by his subordinates." After the house was confiscated, King Jing of Beijing and King of Xiping took care of him. His official position in Rongguo Mansion was restored, and Jia Zheng succeeded him, but failed to restore the family's decline.
