Write an realistic, plausible alternate history scenario set on the world of the alternate history scenario with no references to the real world, OTL, or even to the fact that this is an alternate history scenario after all in the form of a lengthy, descrptive, exposition-filled real documentary history book chapter set in the world of the alternate history scenario, in which during the transformation of the post-Qing, post-Xinhai Revolution military dominated Beiyang Government-ruled federal parliamentary presidental republic of the first Republic of China ruling over Han China into the unitary constiutional imperial royal monarchy of the Empire of China by Yuan Shikai in 1915, Shikai doesn't crown himself Emperor but instead the ruling family of the pre-Qing Ming dynasty, the Han Chinese Imperial House of Zhu, [the Ming dynasty's imperial family of the Imperial House of Zhu] is reenthroned [the Ming dynasty's imperial family of the Imperial House of Zhu] as the Chinese imperial family [the Ming dynasty's imperial family of the Imperial House of Zhu]. Due to the goal of the Xinhai Revolution being to restore the Ming as the government of Han China after the overthrow of the Ming and the reenthroned Imperial House of Zhu abandoning Han Chinese claims on Manchuria, Greater Mongolia, Tuva, East Turkestan and Tibet, meaning that the Empire of China's territory is [the Empire of China's territory] contained [the Empire of China's territory] within the historical eighteen provinces of the legendary Han Chinese Imperial House of Liu-ruled absolute feudal dynastic royal imperial monarchy of the Han dynasty and that Manchuria, Greater Mongolia, Tuva, East Turkestan and Tibet never [Manchuria, Greater Mongolia, Tuva, East Turkestan and Tibet] become a part of post Qing, post-Xinhai Han China, with Manchuria quickly becoming a protectorate [Manchuria] of the Japanese Imperial House of Great Yamato-ruled Great Japanese Empire ruling over Sahlakin and the Kurils, Okinawa the Carolinas and the Marinas, Palau and the Korean peninsula from its [the Great Japanese Empire's] stronghold and [the Greater Japanese Empire's] homebase of the Japanese Home Islands and Taiwan and the Pengu Islands, [Manchuria being an imperial Japanese protectorate] first [Manchuria as a imperial Japanese protectorate] under the rule of the Manchuria based Han Chinese warlord and military junta of the Fengtian Clique that [the Fengtian Clique] occupied both the Beiyang Government and the first Republic of China after the Xinhai Revolution and [the Fengtian Clique] broke away from both the Beiyang Government and the first Republic of China after the formation of the Empire of China in this scenario to [the Fengtian Clique] form an independent Manchurian state and then as a constitutional imperial parliamentary royal monarchy of the Empire of Manchukuo [Manchuria as a Japanese protectorate] ruled [Manchukuo] by [Manchukuo's ruling imperial family] the Qing imperial family, the Manchu Imperial House of Aisin-Gioro after the Fengtian Clique was [the Fengtian Clique] removed [the Fengtian Clique] from power [the Fengtian Clique] in Manchuria, [Manchuria becoming a Japanese protectorate, first under the rule of the Fengtian Clique and then as the Imperial House of Aisin-Gioro-ruled Empire of Manchukuo] along with Greater Mongolia, which [Greater Mongolia] remains under the rule of  the spiritual head of the Gelug lineage of Tibetan Buddhism in Mongolia also holding the title of Bogd Gegeen, making them the top-ranked lama in Mongolia known as the Jebtsundamba Khutuktu as the Bogd Khan [Holy Emperor]-ruled post-Xinhai, Unitary Buddhist absolute monarchy of the feudal Khanate of the Bogd Khanate of Mongolia/Great Mongolian State and [Greater Mongolia] is [Greater Mongolia] never [Greater Mongolia] conquered [Greater Mongolia] by the Soviets, [Greater Mongolia under the rule of the Bogd Khan-ruled Bogd Khanate of Mongolia/Great Mongolian State being a Japanese protectorate alongside Manchuria] although the Japanese later split off Inner Mongolia's Chahar and Suiyan regions from Greater Mongolia to [the Japanese] create the Genghis Khan-descended Imperial House of Borjigin-ruled Mongolian Autonomous Federation/Mengjiang, along with [the reenthroned Imperial House of Zhu] expanding the federalism promoted by the Beiyang government to allow the Chinese provinces within Han China proper autonomy within the confederation of the Beiyang Government and later the Empire of China, [the reenthroned Imperial House of Zhu] even allowing Yunnan to [Yunnan] secede [Yunnan] from Han China and [Yunnan] subsequently restore the pre-Mongol Empire and then pre-Ming Bai-Han Chinese Imperial House of Duan-ruled feudal dynastic royal absolute monarchy of the Daili Kingdom as its [Yunnan's] government, [Yunnan] being [Yunnan] independent [Yunnan] from China from now on, the National Protection War of 25 December 1915 – 14 July 1916 between the Empire of China and the Han nationalist, Han supremacist, Han imperialist and Han expansionist Kuomingtang lead [the Kuomingtang] by its [the Kuomingtang's] founder and the leader of the Xinhai Revolution against the Qing, the Han Chinese doctor turned revolutionary and statesman Dr. Sun Wen, [Wen] known outside Asia as [Wen's other alias] "Dr Sun Yat-Sen" ends [the National Protection War] with the victory of the Empire of China over the Kuomingtang and the then embyroic Nationalist China due to Yunnan being on the side of the Empire of China and Cantonese independence activists and supporters rising in rebellion against Wen/"Yat-Sen" and the KMT in Nationalist China's stronghold of Guangxi and Guangdong. Despite the victory of the Empire of China against the Japanese backed Wen/"Yat-Sen" in Nationalist China, Imperial Japan still maintains its [Imperial Japan's] close ties and [Imperial Japan's] effective de-facto control over the Beiyang Government despite the restoration of the monarchy [the Ming and the Imperial House of Zhu] through the Empire of China in China. 

The Second Sino-Japanese War of 1928 -1947 between Imperial Japan, Manchukuo, Mengjiang, Beiyang China and Nationalist China with Nationalist China being [Nationalist China] backed [Nationalist China] by both the USA and the USSR never happens along with the 1928 Northern Expedition launched by Wen's/"Yat-Sen's" student turned infamous Chinese warlord and later puppet dictator of Stalin in China, Jiang Jieshi aka "Chiang Kai Shek" as Generalissmo of Nationalist China against both the Fengtian Clique and the Beiyang-ruled first ROC with joint Soviet and American help due to Wen/"Yat-Sen" being [Wen/"Yat-Sen"] defeated [Wen/"Yat-Sen"] in the National Protection War and Nationalist China's evolution into an independent Cantonian republic after the National Protection War. As a result, Imperial Japan, Beiyang China, Manchukuo and Mengjiang don't collapse after WW2 and [Imperial Japan, Beiyang China, Manchukuo and Mengjiang] also [Imperial Japan, Beiyang China, Manchukuo and Mengjiang] survive [Imperial Japan, Beiyang China, Manchukuo and Mengjiang] past 1947, [Imperial Japan, Beiyang China, Manchukuo and Mengjiang] lasting  [Imperial Japan, Beiyang China, Manchukuo and Mengjiang] until the present day and beyond. Nationalist China also survives past 1949, [Nationalist China] eventually making up with Imperial Japan, Beiyang China, Manchukuo and Mengjiang and [Nationalist China] helping Imperial Japan liberate the nativized Vietnamesed side branch of the Imperial House of Zhu, the Vietnamese Imperial House of Ngyuen/Ngyuen-dynasty ruled Empire of Vietnam in Vietnam, the Laotian Khun Lo-dynasty ruled Kingdom of Laos in Laos and the House of Norodom-ruled Kingdom of Cambodia in Cambodia from the French colonial occupation of Indochina known as French Indochina in the last days of WW2. After its independence Vietnam makes Cambodia and Laos into protectorates and Nationalist China into an autonomous region, [Vietnam] becoming known as "South China" while the Empire of China is [the Empire of China] called North China.
