Write a realistic, sensible, plausible and alternate history scenario in the form of a historical documentary book chapter set in the world of the alternate historical scenario with no references to this being an alternate history scenario or to the real world timeline at all, in which after the death of the founding leader and the first dictator of the Han nationalist, Han supremacist Chinese Communist Party-ruled People's Republic of China occupying Han China, Inner Mongolia, Tibet, East Turkestan, Yunnan, Guangxi and Guangdong since 1949, Mao Zedong on September 9, 1976,  the pre-Qing Great Ming State/Great Ming Empire/"Ming dynasty" and the Ming dynasty’s imperial family, the Han Chinese Imperial House of Zhu is [ the pre-Qing Great Ming State/Great Ming Empire/"Ming dynasty" and the Ming dynasty’s imperial family, the Han Chinese Imperial House of Zhu] restored [ the pre-Qing Great Ming State/Great Ming Empire/"Ming dynasty" and the Ming dynasty’s imperial family, the Han Chinese Imperial House of Zhu] as the government [ the pre-Qing Great Ming State/Great Ming Empire/"Ming dynasty" and the Ming dynasty’s imperial family, the Han Chinese Imperial House of Zhu] of Han China in the form of a restored Beiyang Government-ruled First Republic of China as a restored Yuan Shikai-formed Empire of China with the descendants of the Imperial House of Zhu replacing Yuan Shikai's descendants as the Chinese imperial family and also being an Islamic emirate akin to those seen in Southeast Asia and the Arab monarchies of the Middle East, following the discovery of a series of documents written by Mao that stated that the eldest surviving male descendant of the Chinese imperial family [the House of Zhu] must succeed him [Mao] as leader of the PRC after his [Mao's] death and that the PRC must be dissolved, with the Ming being restored in Han China as per the goal of the the Xinhai Revolution launched by the Han nationalist and Han supremacist Tongmenhui against the Manchu ruled Manchu Imperial House of Aisin-Gioro-ruled Great Qing Empire in 1911.

Manchuria and Inner Mongolia are the first to break away, with Manchuria restoring the Imperial House of Aisin-Gioro-ruled Empire of Manchukuo and Inner Mongolia restoring the Genghis Khan descended Imperial House of Borjigin-ruled Mongolian Autonomous Federation. In Tibet the Lama-ruled Kingdom of Tibet is restored and in East Turkestan, the  House of Chagatai-ruled Kumul Khanate is [the Kumul Khanate] restored [the Kumul Khanate in East Turkestan], although the joint Soviet-American puppet state of the Han nationalist, Han supremacist, Leninist-Stalinist Kuomingtang-ruled Nationalist China/Second Republic of China in exile on Taiwan since 1949 manages to take Guangxi and Guangdong with the help of both the Americans and the Soviets but revolts in Taiwan cause Nationalist China to lose Taiwan, which [Taiwan and the Pengu Islands] the Americans reluctantly return to Japan in a repeat of the return of Okinawa to Japan on May 15, 1972.

After the chaotic aftermath of Mao's death topples both the Soviet puppet dictatorship of the Workers Party of Korea-ruled Democratic People's Republic of Korea occupying North Korea and the joint US-PRC puppet state of the military dictatorship of the Republic of Korea occupying South Korea, with troops of the now-dissolved DPRK's combined armed forces, the Korean People's Army helping South Korean dissidents and activists fight off American troops in South Korea and Soviet troops in North Korea, causing the Viet Cong to turn on the Soviets, the Americans also return the Korean peninsula to Japan.

Japan makes Manchukuo and the Mongolian Autonomous Federation into protectorates once more and [Japan] enforces an informal tributary status upon the restored Great Ming.

The restored Ming is a provisional absolute imperial royal monarchy  still officially referred to as the "People's Republic of China" in English but having the name "Empire of China" in English from 1976-1979, and then an constitutional imperial federalist democratic absolute royal monarchy with free and fair, multi-party elections via secret ballot from 1980 onwards, being known officially as the Empire of China in both English and Chinese from now on. The restored Ming also flies the Beiyang Government's and the First Republic of China's five-color-flag as its state banner while the restored Ming's state flag while the Ming's sun flag, a orange banner [the Ming sun flag] with a red dot in the center [of the Ming sun flag], [the Ming sun flag] returns to being the unofficial civil flag.

A modified version of the Kuomingtang's Blue Sky, White Sun, and a Wholly Red Earth flag becomes its [the restored Ming State's] naval flag, [the restored Great Ming State] replacing the White Sun with a yellow sun in tribute to the original Ming blue sky and yellow sun flag while the crossed 18-star iron blood flag becomes the Chinese army flag. 

Mao Zedong is seen in both China and the rest of Asia the same way as Franco is seen in Spain and the rest of Europe:  A brutal dictator [Mao and Franco] who [Mao and Franco] fought against communist terrorists [the Spanish Republicans and the KMT] backed [the Spanish Republicans and the KMT] by both the Americans and the Soviets but whose [Franco's and Mao's] actions lead to the restoration of the monarchy [the Bourbon-ruled Kingdom of Spain and the Zhu-ruled Great Ming Empire] after his [Franco's and Mao's] death. Yuan Shikai's descendants are absorbed into the Imperial House of Zhu via intermarriage, concubinage, multiple marriages and adoptions.
