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/Great Ming State/"Ming dynasty" that [the Great Ming Empire/Great Ming State/"Ming dynasty"] had ruled over Han China from [how long the Great Ming Empire's/Great Ming State's/"Ming dynasty"'s rule over Han China lasted for] 1368-1644 is [the Great Ming Empire/Great Ming State/"Ming dynasty"] restored [the Great Ming Empire/Great Ming State/"Ming dynasty"] as the government [the Great Ming Empire/Great Ming State/"Ming dynasty"] 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 the 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 [the surviving Cantonese nationalist elements within the PRC 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 [the Cantonese nationalist within mainland China-KMT alliance] to [the Cantonese nationalist within mainland China-KMT alliance] 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. 

With the KMT now effectively defunct and any dreams of restoring Nationalist control over the Chinese mainland now dead on arrival, Taiwan declares independence from Nationalist China, the USA and the USSR as an independent republic known [independent post-Soviet and post-Nationalist China Taiwan] as [what independent post-Soviet and post-Nationalist China Taiwan calls itself] the Republic of Formosa [independent post-Soviet and post-Nationalist China Taiwan] with former Imperial Japanese Army officer turned pro-democracy politician Lee Teng Hui serving as its [the Republic of Formosa's] first president [Lee Teng Hui]. The Americans, not wanting to face any more embarrassment after the fall of both the PRC on the mainland and Nationalist China in exile in Taiwan, [the Americans] 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 Japanese then make post-Nationalist China Taiwan and the Pengu Islands into the restored Formosa province of Japan.

The restored Nationalist China in Southern China joins ASEAN and [the restored Nationalist China in Southern China] eventually becomes known as the Republic of Cantonia or just Cantonia, with its [the restored Nationalist China in Southern China's] residents being known as Cantonese. 

The now-Yellow Sand society-controlled post-PRC and post-CCP Han China is [the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] recognized as the legitimate Chinese state [the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] and [the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] subsequently receives significant investments as well as economic and developmental aid from the UN and Western Europe, [the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] first coming under the rule of a restored Beiyang Government of the Republic of China as an authoritarian totalitarian regency government [the restored Beiyang Government of the Republic of China ruling over post-PRC and post-CCP Han China] for the restoration of the Chinese monarchy [Great Ming Empire/Great Ming State/"Ming dynasty"] for a couple of months after the balkanization of China due to the Tiananmen Square protests.

The CCP's parent party, the Han nationalist, Han supremacist and Han fascist Young China Party [YCP] named [the YCP] for the Ottoman Empire's infamous "Young Turks", [the YCP] becomes the governing party [the YCP] of the restored Beiyang Government of the Republic of China ruling over post-PRC and post-CCP Han China in a coalition government with other political parties formed after the fall of the PRC. 

 Sometime in 1990, the restored Beiyang Government of the Republic of China ruling over post-PRC and post-CCP Han China is [the restored Beiyang Government of the Republic of China ruling over post-PRC and post-CCP Han China] dissolved and the Empire of China is [the Empire of China] reinstated [the Empire of China] as the government [the Empire of China] of Han China, with Yuan Shikai's descendants 'handing over' control over Han China to the surviving descendants of the Imperial House of Zhu, who [the Zhu descendants] resume their [the Imperial House of Zhu's] role as the Chinese imperial family [the Imperial House of Zhu]. 

The restored Empire of China ruled by the Zhu descendants as its [the restored Empire of China's] imperial family [the Zhu descendants] ruling [the restored Empire of China] over the now-Yellow Sand society-controlled post-PRC and post-CCP Han China is [the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China ruling |the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China| over the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] a unitary provisional absolute imperial royal monarchy from 1990-1992 and [the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China ruling |the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China| over the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] a unitary parliamentary constitutional federalist democratic monarchy [the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China ruling |the Imperial House of Zhu-ruled post-PRC, post-CCP restored Empire of China| over the now-Yellow Sand society-controlled post-PRC and post-CCP Han China] with free and fair, multi-party democratic elections done via secret ballot from 1992 onward. 

The Manchu-Imperial House of Aisin-Gioro-ruled Empire of Manchukuo is [Manchukuo] restored in Manchuria and Outer Manchuria and the 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. 

Both the Soviet satellite dictatorship of the Workers' Party of Korea-ruled Democratic People's Republic of Korea [DPRK] occupying North Korea and the totalitarian military dictatorship of the Republic of Korea [ROK] in South Korea both [the DPRK and the ROK] collapse [the DPRK and the ROK] due to the chaos in the China region caused by the Tiananmen Square protests and the subsequent resumption of the Chinese Civil War spilling over into the Korean peninsula. 

The Korean People's Republic formed by Lyuh Woon-hyung in 1947 is [the Korean People's Republic] restored [the Korean People's Republic] as the government [the Korean People's Republic] of a post-DPRK, post-ROK united Korean peninsula as a neutral state, with pro-democracy, pro-Western elements in both the now-dissolved DPRK and ROK coming together to govern a Korea united for the first time since 1947. 

This restored Korean People's Republic quickly comes under the influence of Japan, which [Japan] makes it [the post-DPRK, post-ROK restored Korean People's Republic] the restored pre-1947 Japanese province of Chōsen in all but name. 

Japan also makes Manchukuo and Mengjiang into protectorates in a repeat of the pre-WW2 and WW2-era situation, and [Japan] also manages to reclaim Sahlakin and the Kurils from the Russians, [Japan] making Sahalkin and the Kurils into the restored Karufuto province.
