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  the Jurchen-Han Chinese Imperial House of Zhu-ruled Great Ming Empire that had ruled over Han China from 1368-1644 is restored as the government of Han China through the return of the Beiyang Government of the Republic of China as the Yuan-Shikai formed Empire of China after the death of Mao Zedong, the founder, first president and fascist dictator of the Han nationalist, Han fascist and Han imperialist Chinese Communist Party-ruled People's Republic of China in September 9, 1976 and Chiang-Kai-Shek, the dictator of the Han nationalist, Han supremacist, Leninist-Stalinist Kuomingtang-ruled joint Soviet-American dictatorship of the Chinese Nationalist State/Second Republic of China/Nationalist of China which had been in exile in Taiwan after its defeat in the Chinese Civil War in 1947, on April 5, 1975, causes the PRC to break apart as Cantonese nationalists and fascists attempt to take over the PRC and Manchurian members of the CCP and PLA's military elite resist this and Nationalist China in exile to be dissolved after Kai-Shek's two sons are assasinated and Taiwan declares independence from both the ROC, USA and USSR as an independent republic. 

The Americans, not wanting to face any more embarrassment after the fall of both the PRC on the mainland and the ROC in exile in Taiwan, return Taiwan and the Pengu Islands to Japan in a manner akin to the return of Okinawa to Japan on May 15, 1972, which the Japanese readily accept. The Soviets waste resources helping the ROC and the KMT fight off the indigenous resistance fighters in Taiwan which causes the Viet Cong to drop Soviet support and uniting Vietnam in favor of helping the Taiwanese fight off the Soviets, the ROC and the KMT and causing the Soviet satellite dictatorship of the Democratic People's Republic of Korea ruled by Kim Il-Sung occupying North Korea to collapse. The pro-Japanese Republic of Korea under former Imperial Japanese Army solider Park-Chung-Hee in South Korea annexes post-DPRK North Korea and restores the pre-DPRK, pre-ROK Korean People's Republic as the government of a united Korea under UN supervision.  After the assassination of Park on 26 October 1979, the Korean Empire that ruled Korea from 1897-1910 is restored as the government of a united Korea, although the new Korean imperial family is supposedly descended from the pre-Joeson Kingdom's Goryeo Kingdom's ruling family, the House of Wang. 

Korea effectively becomes a Japanese province once more in all but name, although the country maintains the official name of the Korean People's Republic.

The Manchu-Imperial House of Aisin-Gioro-ruled Empire of Manchukuo is restored in Manchuria and Outer Manchuria and the Mongolian Genghis-Khan descended Imperial House of  Borjigin-ruled Mengjiang United Autonomous Government/Mongolian Autonomous Federation  returns in Inner Mongolia's Charhar and Suiyan regions under the supervision, direction and mandate of the UN [Mengjiang and Manchukuo] returning to their [Mengjiang's and Manchukuo's] pre-WW2 and WW2-era status as Japanese protectorates [Mengjiang and Manchukuo], again under the supervision, direction, and mandate of the UN. East Turkestan becomes a restored Imperial House of Osman-ruled Ottoman Empire, the regions of Central China once ruled by the Ma family during the post-Yuan Shikai modern warlord era of modern Chinese history, the Second Sino-Japanese War and the Chinese Civil War become an independent Hui state that eventually becomes a restored Mongolian-Manchu-Imperial House of Li-ruled Tang dynasty/Tang Empire and Tibet becomes the Kingdom of Tibet under the theocratic rule of the Llamas. Due to the Viet Cong exhausting itself fighting against the Soviets and the ROC in Taiwan, the Republic of Vietnam and the Republic of Vietnam Armed Forces are able to win the Vietnam War and unite Vietnam under the North, but not before a mysterious explosion topples the South Vietnamese military government and restores the Vietnamese nativized side-branch of the Ming dynasty's Imperial House of Zhu, the Imperial House of Ngyuen/Ngyuen dynasty-ruled Empire of Vietnam to power in Vietnam. Vietnam annexes Laos and Cambodia and then takes Cambodia, and the Spratleys, restoring the Nanyue Kingdom.

Mao Zedong is viewed in China and Asia the same way Franco is seen in Spain and Europe: A brutal dictator who fought against communist terrorists [the Spanish Republicans and the KMT] backed by both the Americans and the Soviets but whose actions lead to the restoration of the monarchy [the Bourbon-ruled Kingdom of Spain and the Zhu-ruled Great Ming Empire] after his death.
