As of the
Jinglong era (707-710) of Wu Zetian's son
Emperor Zhongzong, Zhong Shaojing was serving as the director of imperial gardens (苑總監,
Yuan Zongjian). In 710, Emperor Zhongzong died suddenly—a death that traditional historians believed to be a poisoning carried out by his powerful wife
Empress Wei and her daughter Li Guo'er the
Princess Anle, so that Empress Wei could become "emperor" like Wu Zetian and Li Guo'er could become crown princess. For the time being, Emperor Zhongzong's son by a
concubine,
Li Chongmao the Prince of Wen, was made emperor (as Emperor Shang), and Empress Wei retained power as
empress dowager and
regent. She viewed Emperor Zhongzong's brother
Li Dan the Prince of Xiang and sister
Princess Taiping as threats, and considered killing them. Meanwhile, Princess Taiping and Li Dan's son
Li Longji the Prince of Linzi heard news of this, and therefore considered acting first. They, along with Princess Taiping's son Xue Chongjian (), Zhong, Wang Chongye (),
Liu Youqiu, and Ma Sizong (), planned a coup, and soon launched it, with support from imperial guard soldiers disgruntled at harsh treatment by their commanders Wei Bo () and Gao Song (), Empress Wei's nephews whom she had put in charge. Zhong was set to join the coup with the servants and laborers of the imperial gardens, but almost did not do so as he suddenly hesitated, only resolving to join the coup after his wife pointed out that if the coup failed, he would suffer death anyway. The coup was successful, and Empress Wei and Li Guo'er were killed. Li Dan was made regent, and for his contributions in the coup, Zhong was made
Zhongshu Shilang (), the deputy head of the legislative bureau (中書省,
Zhongshu Sheng), and given the designation
Canzhi Jiwu (), making him a
chancellor de facto. He was also given the honorific title
Yinqing Guanglu Daifu (). The next day, he was given the greater chancellor
de facto designation of
Tong Zhongshu Menxia Sanpin (). == During Emperor Ruizong's reign ==
