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 anti-corruption, anti-nepotism, pro-democracy, democratic reform student-lead Tiananmen Square protests of 15 April 1989 – 4 June 1989 in the Han nationalist, Han fascist and Han imperialist Chinese Communist Party-ruled People's Republic of China against the pro-Han nationalist, Han supremacist, Leninist-Stalinist Kuomingtang-ruled joint Soviet-American puppet, dictatorship of the Chinese Nationalist State/Second Republic of China/Nationalist State of China which [the Chinese Nationalist State/Second Republic of China/Nationalist State of China] had been in exile in Taiwan after its [Nationalist China's] defeat in the Chinese Civil War in 1947, pro-Soviet, pro-American Cantonese nationalists and [Cantonese] supremacist elements within China that had taken control of China ever since the rise of Deng Xiaoping to power in the PRC and CCP on 22 July 1977 succeeding [the Tiananmen Square protests of 15 April 1989 – 4 June 1989 in this timeline] due to [why he Tiananmen Square protests of 15 April 1989 – 4 June 1989 succeed |the Tiananmen Square protests of 15 April 1989 – 4 June 1989| in this timeline] the failure of said surviving Cantonese nationalist elements within the PRC to suppress the Ming restorationist millennial religious sect known as the Yellow Sand Society in 1980, allowing the Yellow Sand Society to survive and [the Yellow Sand] continuing to gather support from disgruntled Han Chinese nationalists, Ming monarchists and fascist's within the PRC, leading to a short resumption of the Chinese Civil War, this time pitting the Cantonese nationalists that have taken over both the PRC and the CCP, the remaining KMT loyalists and supporters in exile on Taiwan, the USA and the USSR against the Yellow Sand Society and the student associations leading the Tiananmen Square protests of 15 April 1989 – 4 June 1989, which [the resumed Chinese Civil War] the latter [the Yellow Sand Society and the students protesting at Tiananmen Square] resoundingly win, although this leads to the dissolution of the PRC and the subsequent liberation of East Turkestan in Xingjiang, the Kingdom of Tibet in Tibet, Inner Mongolia and Manchuria from the post-1947 occupation of these lands [East Turkestan, Manchuria, Tibet and Inner Mongolia] by the Han Chinese via the PRC. The Cantonese nationalist within mainland China-KMT alliance manages to hold on to the core of Southern China [Guangdong, Guangxi, Hainan and Yunnan] with joint US-Soviet aid, [The Cantonese nationalist within mainland China-KMT alliance subsequently] forming a restored Nationalist China within these regions [Guangdong, Guangxi, Hainan and Yunnan]. 

This restored Nationalist China in the Cantonia region doesn't last long however, as Yunnan manages to break free and [Yunnan] subsequently restores the Imperial House of Duan-ruled Dali Kingdom as its [post CCP, post-restored Nationalist China's Yunnan's] government. Cantonian independence activists also manage to infiltrate the restored Nationalist China in Southern China's government and [the Cantonian independence activists] subsequently suppress the Cantonian nationalist-KMT loyalist/restorationist factions in the restored Nationalist China in Southern China, [the Cantonian independence activists] making the restored Nationalist China an independent Cantonian republic in all but name. 

These Cantonian independence activists then negotiate a ceasefire with the now-Yellow Sand society-controlled post-PRC and post-CCP Han China, the restored Kingdom of Tibet in Tibet, the restored Daili Kingdom in post-CCP, post-restored Nationalist China Yunnan, the once again independent, post-CCP, post-PRC East Turkestan, the once again independent, post-CCP, post-PRC Manchuria and post-CCP Inner Mongolia with the approval of and under the oversight of both the UN and the ASEAN nations that essentially brings the death knell to a united "Greater Han China" [under either the KMT-ruled Nationalist China or the CCP-ruled PRC] and confirms the status of these nations [the restored Nationalist China in Southern China, the now-Yellow Sand society-controlled post-PRC and post-CCP Han China, the restored Kingdom of Tibet in Tibet, the restored Daili Kingdom in post-CCP, post-restored Nationalist China Yunnan, the once again independent, post-CCP, post-PRC East Turkestan, the once again independent, post-CCP, post-PRC Manchuria and post-CCP Inner Mongolia] as independent, sovereign nation-states under international law. Deng Xiaoping and the rest of the post-1947 Cantonian nationalist clique in mainland China that had [the Cantonian nationalist clique in post-1947 mainland China ] taken over the CCP and PRC  after the death of Mao Zedong, the founder [Mao], first president [Mao] and fascist dictator of the CCP-ruled PRC on [when Mao died] September 9, 1976, [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China] are [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China] handed over to the UN along with the KMT remnants and restorationists and [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China along with the KMT remnants and restorationists] subsequently tried  [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China along with the KMT remnants and restorationists] for mass murder and genocide at the Hague, along with the Khmer nationalist and Khmer expansionist Khmer Rouge in Cambodia and  [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China along with the KMT remnants and restorationists] are  [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China along with the KMT remnants and restorationists] subsequently either exectuted or  [Deng Xiaoping and the rest of the Cantonian nationalist clique in post-1947 mainland China along with the KMT remnants and restorationists] given life without parole on the ruling of the Hague.
