During Chancellorship
In 784, because the general Li Huaiguang also rebelled, Emperor Dezong fled further to Liang Prefecture (梁州, in modern Hanzhong, Shaanxi), and Jiang Gongfu accompanied him. On the way to Liang Prefecture, Emperor Dezong's oldest daughter Princess Tang'an died at Chenggu (城固, in modern Hanzhong). After Emperor Dezong reached Liang Prefecture, he wanted to build a pagoda for Princess Tang'an and bury her with great wealth. Jiang submitted a petition stating:
Soon, the capital will be recaptured, and the princess will be able to be reburied properly. We are now on the road, and we need to be frugal and use the money on the soldiers.Emperor Dezong became angry and wanted to remove Jiang. Despite the intercession of Emperor Dezong's trusted advisor Lu Zhi, Emperor Dezong soon removed Jiang and made him a member of the staff of his crown prince Li Song.
