rule of the Kuomingtang-ruled Nationalist China sometime in 1914, [the Beiyang Government ruling over the sixteen provinces of Han] since the 1911-1912 Xinhai Revolution that [the Xinhai Revolution] toppled the Great Qing Empire and [the Xinhai Revolution] subsequently made the Beiyang Government as the post-1912, pre-1915 and post-1916, pre-1928 federal presidential parliamentary republic of the

establishment of a preparatory committee on 19 August 1915, with more and more "petition groups" writing petitions demanding a change in the state system of the Beiyang Government, with Yuan Shikai receiving the "National Protector Envoy Encouraging Jin to Proclaim Emperor", which was signed by governors of all provinces in the country, then the establishment of the "Preparatory Committee" which convened provincial civil and military officials and chambers of commerce to the Beiyang Government's and the Great Qing Empire's shared capital of Beijing to discuss state affairs, with most of them expressing the need to change the state system of the Beiyang Government, on 23 August 1915, with Cai E leading the soldiers to petition for imperialism on 25 August 1915, which leads to the petition to change the state system of the Beiyang Government [from the first Republic of China to a constitutional monarchy], on the Beiyang Government's National Assembly's Senate's opening ceremony on 1 September 1915, with petition groups supporting the monarchy submitted petitions to the Beiyang Government's National Assembly's Senate, setting off a wave of petitions for the implementation of a constitutional monarchy in the following days, with the formation of the "National Petition Federation" on the 19th of September 1915 to encourage the organization of a petition group and submit a third petition to the Beiyang Govenment's National Assembly's Senate, demanding a national meeting, where representatives from the whole country are elected to decide on state issues, with the Beiyang

establishing a ceremony preparation office on 29 November, 1915 to prepare for the enthronement and select a date to ascend the throne, with the Beiyang Govenment's National Assembly's Senate's 1993 national representatives subsequently voting on the change of the Beiyang Government's state system on 11 December, 1915 with the Beiyang Govenment's National Assembly's Senate unanimously approving the constitutional monarchy as a result, with the representatives of the provinces requesting Yuan Shikai to be the emperor of the Chinese Empire for the first time the same day, with Shikai accepting

with the right to dissolve the National Assembly, "Great Emperor of the Chinese Empire" under the combined era and regal name of [Yuan's combined regal and era name as the first "Great Emperor of the Chinese Empire"] Hóngxiàn ["Promote the constitution"] the very same day, with Shikai as the Hóngxiàn Emperor of the Chinese Empire conferring five-level knighthoods on provincial generals, patrol envoys, military envoys, garrison envoys, division commanders and those with military power in the fifteen provinces of Han under the rule of the main branch of the Beiyang Government on December 21,

China after the Empire of China was dissolved lasted for] 1928, [the unification of the PRC and Nationalist China into a united Chinese Republic, more specifically a restored Beiyang Government] akin to the reunification of Germany after the fall of the Berlin Wall via the Federal Republic of Germany in West Germany absorbing the Soviet puppet state of the German Democratic Republic in East Germany into itself in 1989, with the PRC being the Chinese version of the FRG and Nationalist China being the Chinese version of the DDR?  The restored Beiyang Government formed by the reunification of the PRC and the KMT-ruled Nationalist China into a single Chinese Republic would initially be a restored first Republic of China from 1989 to 1990 and then would become a restored Empire of China by 1991 due to the immense monarchist sentiment in China, but Yuan Shikai's descendants wouldn't become the latest Chinese Imperial family, the descendants of the Ming dynasty's reigning Imperial family, the Han Chinese crypto-Sunni Muslim Imperial House of Zhu, would be this restored Empire of China's reigning Imperial family due to Ming restorationist romanticist millerian monarchist sentiment in China.
