Write a realistic, plausible alternate history scenario in the form of a history book chapter completely set in the world of the alternate history secenario with absolutely no references to real life, in which the 1989 Tianamen Square protests in the CCP-ruled mainland China become a modern-day combination, repetition and repeat of both the Taiping Rebellion and the Xinhai Revolution with the sixteen provinces of the Han dynasty excluding Guangdong and Guangxi, Guangdong and Guangxi, Northwestern Han China's primarily Hui Muslim provinces of  Qinghai, Gansu and Ningxia, Inner Mongolia, East Turkestan, Tibet and Yunnan all breaking away from the CCP's strongholds and homebases of Shaanxi and Manchuria and [the sixteen provinces of the Han dynasty excluding Guangdong and Guangxi, Guangdong and Guangxi, Northwestern Han China's primarily Hui Muslim provinces of Qinghai, Gansu and Ningxia, Inner Mongolia, East Turkestan, Tibet and Yunnan ] becoming independent sovreign states, but Nationalist China returns from its exile from Taiwan and the Pengu Islands and  subsequently retakes the sixteen provinces of the Han dynasty excluding Guangdong and Guangxi after the collapse of the PRC, but this doesn't last as Nationalist China is kicked off both Taiwan and the Pengu Islands and becomes stuck in the sixteen provinces of the Han dynasty excluding Guangdong and Guangxi, the CCP is overthrown in Manchuria and the Fengtian Clique, although ruled by the descendants of the former Qing reigning imperial family, the Manchu Imperial House of Aisin-Gioro as combined warlords of Manchuria and military dictators of the Fengtian Clique in collaboration with the remnants of the Qing imperial court instead of the descendants of Zhang Zhuolin or his son, Zhang Zhuolin, returning to Manchuria to resume leadership of the Fengtian Clique, is restored in Manchuria after the CCP's fall although this restored Fengtian Clique ruled by the Aisin-Gioro descendants and the Qing Imperial Court instead of the Zhang family quickly transitions to becoming a restored, modernized version of Japan's pre-WW2 and WW2 era protectorate of the Empire of Manchukuo in Manchuria, East Turkestan restores the Kumul Khanate ruled by the side branch of the Genghis Khan descended, Mongolian Imperial House of Borjigin as its government after the fall of the PRC, Tibet comes under the theocratic Buddhist rule of the Llamas once more after the fall of the PRC, and Yunnan comes under the rule of a restored, contemporary version of the Yunnan Clique, which transitions towards becoming a restored Daili Kingdom ruled by the descendants of the Daili Kingdom's reigning royal family, the Bai-Han Chinese Imperial House of Duan,  Qinghai, Gansu and Ningxia all [ Qinghai, Gansu and Ningxia] become a restored, contemporary version of Xibei San Ma with the descendants of the Ma clan regaining their ancestors positions as warlords of  Qinghai, Gansu and Ningxia and military dictators of Xibei San Ma, and Nationalist China once more in the sixteen provinces of Han China after the fall of the PRC being taken over by the remnants of the Anhui Clique and the Anhui Clique's political wing, the Anfu Club and the remnants of the Anhui Clique's financial wing, the New Communications Club in coincidence with and later secret collaboration with with the Ming restorationist, Ming monarchist, adhering to Militant self-defense and tax resistance and traditional Chinese  Heterodox folk religion rural secret society and folk religious sect in Northern Han China's Henan, Shandong, Hebei provinces known as the Yellow Sand Society before the Beiyang Government, or more specifically the Beiyang Government's short lived form as the Empire of China founded and lead by Yuan Shikai in  1915, is restored as the government of Han China, albiet in a modern, contemporary, revitalized form and with the descendants of the Ming dynasty's reigning imperial family, the Imperial House of Zhu, being enthroned as the restored Empire of China's reigning imperial family instead of Yuan Shikai's descendants formally becoming the Chinese modern day reigning imperial family, with the Anhui Clique remnants still effectively managing China and effectively becoming the Chinese local government while the Anfu Club remnants effectively controlled Chinese politics and the Yellow Sand Society became intertwined with the restored Beiyang Government governing the restored Empire of China even as the Hui Muslims became the dominant economic, political and cultural force in the restored Empire of China, mass converting the Han Chinese and Cantonese in Han China and forcing the descendants of the Imperial House of Zhu to reconvert to Sunni Islam, making the restored Empire of China an Islamic Sultanate in all but name with Chinese Buddhism and various aspects of Chinese folk religion being cleverly reinterpreted in order to get the Han Chinese and Cantonese in Han China to convert to Sunni Islam and scholars being sent to Saudi Arabia, Jordan and Qatar to copy and study the political and religious structures of these countries to be reinterpreted in a Chinese, but Hui-influenced and still Islamic context. This gave it the nickname "the Saudi Arabia of East Asia" to both East Asians and Westerners, which isn't helped by the fact that the Ming Sun and Moon Flag, an orange banner with a white circle in the middle representing the moon with another red circle in the far left corner of the white circle in the middle of the Sun and Moon Flag, became the official civil banner and national ensign of the restored Empire of China with the Beiyang Government's five coloured flag, more specifically the initial Empire of China's modified five coloured flag with the five coloured flag's red stripe as a saltire still being reused in a civil and national context but with the Beiyang Government's Twelve Symbols national emblem, which is the restored Empire of China's national emblem in the middle and the Kuomingtang's and thus Nationalist China's Blue Sky, White Sun, and a Wholly Red Earth flag being used as the restored Empire of China's naval jack, but with the Kuomingtang's White Sun in the Blue Sky, White Sun, and a Wholly Red Earth being replaced with a red inner rayed, white outer rayed,yellow sun with a red halo surrounding the yellow sun and the red inner rays being outside the red halo, in the extreme corner of a large white moon in the center of to represent an eclipse with the Chinese character for "Ming" in the Middle of the yellow Sun.

Like the initial Empire of China created by Yuan Shikai, this restored Empire of China is known as the Republic of China in English but the Empire of China in traditional Chinese, or simply as the actual name of the Ming dynasty, 'the Great Ming State" in Traditional Chinese due to the Zhu descendants being its reigning imperial family instead of Yuan Shikai's descendants.

The restored Empire of China also has another official name, the Empire of Hanchukuo due to heavy Japanese support 

Japan, which continued on its post-WW2, starting in the 1950s economic, military, cultural and economic growth along with massive industrial and technological development that reached a cresendo in the 1980s and peaked in the 1990s both in real life in this timeline into the early 21th century and beyond, never having the "Lost Decade" or 'the Plaza Accords" in this timeline and growing to become an industrial, economic, military and cultural superpower not just in East Asia, and the world from the 1980s onwards, reclaimed Taiwan and the Pengu Islands after Nationalist China reclaimed Han China after the collapse of the PRC and was subsequently kicked out of both Taiwan and the Pengu Islands, being stuck in Han China before being replaced by the restored Ming dynasty as the government of post-PRC of Han China, with the Japanese subsequently reclaiming the entire Korean peninsula after the chaos in Han China spread to Korea and toppled the DPRK in North Korea and the ROK in South Korea, and Sakhalin and the Kurils after the Soviets couldn't defend the former just as the Ming dynasty was being restored as the government of China and restored the executive power of the reigning Japanese imperial family, the supposedly Shinto pantheon-descended Imperial House of Great Yamato over both the Japanese local and national government as China fell into chaos after the fall of the PRC, restoring the pre-1947 Japanese Empire as the government of not only Japan, but Taiwan and the Pengu Islands, the Korean peninsula and Sahlakin and the Kurils by the time 1990 rolls around. 

Japan also restored the Qing Imperial family, the Manchu Imperial House of Aisin-Gioro-ruled Empire of Manchukuo in Manchuria and the Genghis Khan-descended Mongolian Imperial House of Borjigin-ruled Mongolian Autonomous Federation/Mengjiang in Inner Mongolia's Chahar and Suiyan provinces as buffer states against the resurgent Chinese warlords after the collapse of the PRC and Nationalist China's subsequent reconquest of Han China before the restored Empire of China replaced Nationalist China as the government of Han China

Due to the Beiyang Government's Japanophilic inclinations and being easily manipulated by Japan, Japan was able to make the restored Ming dynasty into a protectorate ofJapan as well, with the JSDF and Ming and Manchurian troops all training together.
