Is “Verification of the figure's deeds” true?

Official histories such as the 'Annals of Taizong, Volume 2' record: 'Except for the ten abominations, officials guilty of corruption, and premeditated murder, death sentences were commuted and reduced, those sentenced to exile and below were released, and the people of Jiang and Zhe provinces were exempted from overdue taxes. On Gengxu, the Double Ninth Festival, he gave a banquet for close ministers at Li Fang's residence, and summoned the princes and military governors to feast and shoot in the garden. That evening, the Prince of Chu's palace caught fire. On Xinhai, Prince Yuanzuo of Chu was deposed and made a commoner, and sent to Junzhou. On Dingsi, the officials requested that Yuanzuo be allowed to stay in the capital for medical treatment.' The historical novel 'Chapter 14' also records this.
