Abstract: In the process of Yuan Shikai launching the Restoration of Monarchy, Chou An Hui (“筹安会”) took the lead in proposing that the Republic of China should be changed into a constitutional monarchy in the future. Diplomat Wang Rongbao pointed out that the Republic of China should choose to compete with the nominal emperor or the president’s hereditary state system, but was strongly criticized by Chou An Hui and the medias. Finally, Yuan Shikai decided to adopt the monarchy as the state system option of China in the future. At that time, the debates on these three kinds of state systems construction had great impacts, but they were rarely concerned by researchers.
