capably." However, he did not take Song's warning either. During Emperor Xuanzong's reign Later in 712, Emperor Ruizong passed the throne to Li Longji, who took the throne as Emperor Xuanzong, but Emperor Ruizong continued to wield actual power as Taishang Huang (retired emperor) at Princess Taiping's urging. Xiao Zhizhong was soon made the minister of civil service affairs (吏部尚書, Libu Shangshu), and in spring 713 was made Zhongshu Ling again, and again created the Duke of Zan. Soon thereafter, the work Xingzuxilu (姓族系錄), which compiled the family trees of prominent clans, edited by Xiao, Dou Huaizhen, Wei Zhigu, Cui Shi, Lu Xiangxian, Liu Cong (柳沖), Xu Jian (徐堅), and Liu Zixuan, was completed, and all of them were awarded with silk. By 713, it was said that Princess Taiping, Dou, Cen Xi, Xiao, Cui; along with other officials Xue Ji, Li Jin (李晉) the Prince of Xinxing (a grandson of Li Deliang (李德良), a cousin of Tang's founder Emperor Gaozu), Li You (李猷), Jia Yingfu (賈膺福), Tang Jun (唐晙); the generals Chang Yuankai (常元楷), Li Ci (李慈), and Li Qin (李欽); and the monk Huifan (惠範), were plotting to overthrow Emperor Xuanzong. It was further said that they discussed, with the lady in waiting Lady Yuan to poison the gastrodia elata that Emperor Xuanzong routinely took as an aphrodisiac. When this alleged plot was reported to Emperor Xuanzong by Wei, Emperor Xuanzong, who had already received advice from Wang Ju (王琚), Zhang Shuo, and Cui Riyong to act first, did so. He convened a meeting with his brothers Li Fan (李範) the Prince of Qi, Li Ye (李業) the Prince of Xue, Guo Yuanzhen, along with a number of his associates — the general Wang Maozhong (王毛仲), the officials Jiang Jiao (姜皎) and Li Lingwen (李令問), his brother-in-law Wang Shouyi (王守一), the eunuch Gao Lishi, and the military officer Li Shoude (李守德) — and decided to act first. On July 29, Emperor Xuanzong had Wang Maozhong take 300 soldiers to the imperial guard camp to behead Chang and Li Ci. Then, Jia, Li You, Xiao, and Cen were arrested and executed as well. It was said that Xiao was thrifty in his living style and free of corruption, but did little to give his wealth to others or to host guests, and therefore his salaries were saved. When he was executed, he had considerable properties that were confiscated. Notes
