Later in 626, Emperor Taizong had Li Jiancheng and Li Yuanji reburied with honors due imperial princes. Wang Gui and Wei Zheng requested permission to accompany Li Jiancheng's funeral procession, and Emperor Taizong approved—and further expanded the approval to an order that all of Li Jiancheng's and Li Yuanji's staff members participate in the funeral processions.
