Write an realistic, plausible alternate history scenario set on the world of the alternate history scenario with no references to the real world, OTL, or even to the fact that this is an alternate history scenario after all in the form of a lengthy, descrptive, exposition-filled real documentary history book chapter set in the world of the alternate history scenario, in which the Imjin Wars of May 23, 1592 – December 16, 1598 launched [the Imjin Wars] by the hereditary military dictatorship of the Ashikaga shogunate de-facto lead by Toyotomi Hideyoshi-ruled feudal Japan against the satelite state and tributary kingdom of Great Joeson ruled by the partially Han Chinese Korean House of Jeonju Yi in Korea and the state it [Great Joeson] was [Great Joeson] a vassal [Great Joeson] to,  the Han Chinese Imperial House of Zhu-ruled Ming dynasty ruling over both Han China and Cantonia, [the Imjin Wars] end in a victory for feudal Japan, with Joeson being dissolved and the Korean peninsula essentially [the Korean peninsula] becoming a protectorate [the Korean peninsula] of Japan,  and the Ming dynasty essentially becoming a Japanese satellite state in the peace treaty signed in the feudal Japanese capital of Kyoto, with Hideyoshi taking the last King of Joeson before the Imjin War's Seonjo's daughter, Princess Jeongmyeong as his [Hideyoshi's] latest concubine. 

The position of King of Korea still exists and Korea is a kingdom de-jure, but the Japanese revive the pre-Joeson Korean Royal House of Wang -ruled Goryeo Kingdom as the local governance of post-Joeson Korea. The Japanese eventually [the Japanese] dissolve the restored Goryeo Kingdom and [the Japanese] annex the Korean peninsula into Japan as the Japanese province of Chōsen. 


In the aftermath of the victory over the Ming and the absorption of the Korean peninsula into Japan, the Japanese Imperial Family, the Imperial House of Great Yamato/Minamoto dynasty, decides to use this opportunity to reclaim the power it [the Imperial House of Great Yamato/Minamoto dynasty] has [the Imperial House of Great Yamato/Minamoto dynasty]  lost to the shoguns and the samurai class over the years and [the Imperial House of Great Yamato/Minamoto dynasty] regaining executive control of the Japanese government, essentially making Hideyoshi's roles of Chief Advisor to the Emperor and Chancellor of the Realm into a position akin to the Prime Minister in Western European countries or the Reichkanzler in the Germanic lands while using the excuse of purging the newly claimed Korea of pro-Chinese Confucianist and neo-Confucianist elements, native Korean shamanism as well as the power of Korea's native aristocracy, the yangaban as well as freeing the mostly enslaved Korean population and making the Korean commoners long oppressed by both the yangaban and the  House of Jeonju Yi into Japanese citizens during the integration of post-Joeson Korea into feudal Japan as a means of restoring the imperial system of government in Japan before the establishment of the feudal shogunates in a modern context, although the basic governmental style and social structures of the shogunate remain unchanged. 

Hideyoshi then replaces Confucianism and neo-Confucianism along with native Korean shamanism in post-Joeson Korea, with the Japanese state religion of Shinto, Buddhism and even Christianity, which mostly succeeds as the yangaban have [the yangaban] been replaced with Japanese daimyō [feudal lord/s during Japan's feudal period under the shogunates |daimyō|] and the rediscovery of the native Korean Hangul script for writing the Korean language by the Japanese and its [Hangul's] promotion by the Japanese as the way of writing Korean over the Chinese script known as Hanja used by the now-deposed Joseon royal family and the Yangaban for writing in Korean with Nihongo [the Japanese language/Japanese |Nihongo|] and Kanji [the Chinese characters used to write Nihongo |Kanji|] also being promoted in post-Joeson Japanese Korea. 

He [Hideyoshi] also conquers Sahlakin and the Kurils, which [Sahlakin and the Kurils] become the Japanese province of Karufuto

By the time Hideyoshi dies on  September 18, 1598, with his [Hideyoshi's] nephew Toyotomi Hidetsugu succeeding him [Hideyoshi] as both Chief Advisor to the Emperor and Chancellor of the Realm and his [Hideyoshi's] young son Toyotomi Hideyori next in line to succeed both Hideyoshi and Hidetsugu as Chief Advisor to the Emperor and Chancellor of the Realm, with the then-reigning Japanese Emperor Go-Yōzei using this as an excuse not to appoint another shogun until Tokugawa Ieyasu attempts to take control of Japan from Hidetsugu and nearly reopens the Sengoku period.  

Go-Yōzei then appoints Ieyasu as shogun on March 24, 1603, causing the start of the Tokugawa shogunate and forces Ieyasu not to break the arranged marriage between Hideyori and Ieyasu's granddaughter Senhime, with the intention of making their [Hideyori's and Senhime's] first male child into the next shogun after Ieyasu's son Tokugawa Hidetada and also with the intention of uniting the Toyotomis and Tokugawas into a single family, securing the line of shogunal succession while ensuring that actual power in the Japanese government remains within the Imperial House of Great Yamato/Minamoto dynasty. 

While this is going on Japan continues to improve and develop its [Japan's] firearms and artillery technology, [Japan] also continuing to improve its [Japan's] naval might while [Japan] solidifying the Ming dynasty's status as an unofficial Japanese vassal and satellite state in a reversal of the usual relationships between China and Japan through joint military exercises, suppression of bandits and would-be usurpers in Cantonia and the deportation of yangaban and Sinophilic House of Jeonju Yi members to Ming-controlled Han China. 

The Tokugawa shogunate still maintains its position of isolation from the rest of the world, although this is challenged by the rise of the Jurchen tribes from Manchuria and Outer Manchuria and their [the Jurchen's] subsequent conquest of Han China proper and Cantonia from Manchuria. The Japanese initially support the Ming in the fight against the Jurchens but realize that the conflict will eliminate anti-Japanese elements in China and so allow the Japanese to maintain power in East Asia. 

The Jurchens conquer much of northern China and even parts of Central China, [the Jurchens] subsequently establishing the Manchu-Imperial House of Aisin Gioro-ruled, Manchu dominated Great Qing Empire ruling [the Great Qing Empire] over Han China, Guangdong, Guangxi, East Turkestan, Inner and Outer Mongolia, Tibet, Shanxi and Yunnan from Manchuria while the rump state of the Ming in southern Central China and Cantonia becomes the Southern Ming, still under Japanese protection. 

The half-Japanese Han China pirate and explorer Zheng Sen, [Sen] better known as [Sen's more famous name] Koxinga, [Koxinga] still establishes the Ming satelite state/rump kingdom of the Kingdom of Tungning on March 30, 1661 – February 1, 1662 in Taiwan and the Pengu Islands, but since his [Koxinga's] mother, Princess Minamoto Matsu of the Imperial House of Great Yamato aka Tagawa Matsu is [Princess Matsu] closer to her [Matsu's] family [the Imperial House of Great Yamato/Minamoto dynasty] and the Southern Ming is [the Southern Ming] a Japanese puppet state [the Southern Ming] in this scenario, the Kingdom of Tungning is a Japanese puppet state [the Kingdom of Tungning] in all but name. 

When the Great Qing Empire sets out to [the Great Qing Empire] conquer the Tungning Kingdom from 1682-1683, Japan annexes the Tungning Kingdom and [Japan] subsequently makes Taiwan and the Pengu Islands into the Japanese province of Formosa. 

The Southern Ming conquers Indochina [Vietnam, Cambodia and Laos, [the Southern Ming] using the opportunity to [the Southern Ming] genocide the Vietnamese along with the indigenous Cantonese people of Guangdong and Guangxi and [the Southern Ming] subsequently absorb the surviving Vietnamese into the Han people and [the Southern Ming] committing a near successful genocide of the Cantonese, Laotians and Cambodians, although this doesn't stop the Great Qing Empire from [the Great Qing Empire] conquering it [the Southern Ming] in 1662. 

East Asia is [East Asia] then [East Asia] locked into a cold war between the Great Qing Empire and the Tokugawa shogunate, with the Tokugawa shogunate ruling the waves and [the Tokugawa shogunate] dominating trade and the Great Qing Empire being [the Great Qing Empire] the great land power [the Great Qing Empire] of East Asia. The Great Qing Empire fills the depopulated Cantonia [Guangxi and Guangdong]  and Indochina with Jurchen settlers from Manchuria and Han from Han China in order to better control and manage the region [Cantonia and Indochina], although this backfires on the Great Qing Empire as many of the Han deportees are devout Sunni Muslims and Ming restorationists. 

What remains of the Cantonese, Vietnamese, Laotians and Cambodians are absorbed into the now mostly Manchurian and Han population, with the descendants of the settler-colonists absorbing what little remains of the Indochina and Cambodia region's language, culture and history and slowly beginning to think of themselves as native to the region [Cantonia and Indochina] as the centuries go by, [the descendants of the settler colonists] maintaining a hybrid of their ancestral Manchu and Han customs, religion and culture and that of the now extinct indigenous people of Cantonia and Indochina. 

The Great Qing Empire sells off Indochina to the French supremacist, French imperialist, fascist, imperialist, post-Napoleonic dictatorship of the Unitary parliamentary presidential republic of the Third French Republic ruling over France in 1858, which [Indochina] becomes the French colonial protectorate of French Indochina. The British Empire and the Third French Republic still conduct the 4 September 1839 – 29 August 1842 and 8 October 1856 – 24 October 1860 Opium Wars against the Great Qing Empire however. 

the 1868 Meiji Restoration in the Japanese Tokugawa clan-ruled de jure absolute imperial royal monarchy but de facto feudal hereditary military dictatorship of the Tokugawa shogunate that [the Tokugawa shogunate] ruled [the Tokugawa shogunate] over the Japanese Home Islands and Okinawa that [the Meiji Restoration] abolished the rule of the shoguns and the feudal system over Japan and [the Meiji Restoration] lead to the Japanese imperial family, the Japanese Imperial House of Great Yamato/Minamoto dynasty, [the Japanese Imperial House of Great Yamato/Minamoto dynasty as a result of the Meiji Restoration] regaining executive control over the Japanese government [the Meiji Restoration] leading to the development of a democratic parliamentary system in Japanese politics and [the Meiji Restoration] paving the way for the industrial and military development that made Japan into a regional and then a world superpower, along with [the Meiji Restoration] leading to the formation of the Great Japanese Empire/Empire of Great Japan/Third Japanese Empire/Imperial Japan/Empire of Japan, [the Meiji Restoration] still [the Meiji Restoration] occurs but is [the Meiji Restoration] instead [the Meiji Restoration] a compromise [the Meiji Restoration] between the liberal, social democractic and progressive reformers who support the Japanese imperial family [the Imperial House of Great Yamato/Minamoto dynasty] and the conservative, traditional aristocrats and merchants who support the de-facto Japanese royal family [the Tokugawa clan], with the Imperial House of Great Yamato/Minamoto dynasty still [the Imperial House of Great Yamato/Minamoto dynasty] regaining executive control over the Japanese government, but the reigning heads of the Tokugawa clan are [the reigning heads of the Tokugawa clan] not  [the reigning heads of the Tokugawa clan]  displaced  [the reigning heads of the Tokugawa clan]  from their [the Tokugawa clan's reigning heads'] role as shoguns [barbarian-killing generalissmos |shoguns|, the hereditary military dictators |shoguns| akin to the absolute monarchs of post-Rennissance Europe who |the shoguns| were the de-facto leaders of Japan during the period of feudal rule under the military dictatorship of the various shogunates of Japan from 1192-1868] but instead [the reigning heads of the Tokugawa clan] becoming more akin to the Reichskanzlers [Realm Chancellors/Imperial Chancelors/Chancelors of the Realm |Reichskanzlers|] of the German Royal House of Hohenzollern-ruled Kingdom of Prussia-dominated German Empire and the Swiss-Austrian Imperial House of Habsburg-Lorraine-ruled Austria-Hungarian Empire and the constitutional European royal monarchs of the post-Napoleon era. 

The 1911-1912 Xinhai Revolution against the Great Qing Empire] launched [the Xinhai Revolution] by [who launches the Xinhai Revolution] a coalition of the Han Nationalist, Han supremacist and Han expansionist Tongmenghui and with Cantonese independence and Cantonese nationalist groups against the Great Qing Empire, [the Xinhai Revolution] remains steadfast in its [the Xinhai Revolution's] goal of [what the aim of the Xinhai Revolution was] "Overthrow Qing, restore Ming", which ["Overthrow Qing, restore Ming"] meant ["Overthrow Qing, restore Ming"] that [the meaning of the slogan "Overthrow Qing, restore Ming" during the Xinhai Revolution]  the pre-1644, pre-Great Qing Empire, Han Chinese Imperial House of Zhu-ruled feudal imperial dynastic absolute dynasty royal monarchy of  the Great Ming State/Empire of the Great Ming/Great Ming/"Ming dynasty" would [the Great Ming State/Empire of the Great Ming/Great Ming/"Ming dynasty"] be [the Great Ming State/Empire of the Great Ming/Great Ming/"Ming dynasty"] restored [the Great Ming State/Empire of the Great Ming/Great Ming/"Ming dynasty"] as the government [the Great Ming State/Empire of the Great Ming/Great Ming/"Ming dynasty"] of Han China proper  after the overthrow of the Great Qing Empire, with the stratocratic [military-ruled/military dominated |stratocratic|] Beiyang Government of the federal parliamentary presidental republic under military dictatorship of the first Republic of China ruling [the Beiyang Government-ruled first Republic of China] over post Xinhai, post-Qing Han China never [the Beiyang Government-ruled first Republic of China] being  [the Beiyang Government-ruled first Republic of China] a Republic  [the Beiyang Government-ruled first Republic of China] upon its [the Beiyang Government-ruled first Republic of China] formation in [when the Beiyang Government-ruled first Republic of China was |the Beiyang Government-ruled first Republic of China| formed] on 10 March 1912 but [the Beiyang Government-ruled first Republic of China] instead  [the Beiyang Government-ruled first Republic of China] always being  [the Beiyang Government-ruled first Republic of China] the Empire of China formed by the top dog in the Great Qing Empire's combined naval, aeiral and ground combat forces, the New Army turned rising star in the Beiyang-ruled ROC's political establishment after the Xinhai Revolution and eventually first president of the first Republic of China, the Han Chinese Yuan Shikai on [when Shikai transformed the Beiyang Government-ruled first Republic of China into the Empire of China] 12 December 1915 in OTL, with the Imperial House of Zhu being [the Imperial House of Zhu] reenthroned [the Imperial House of Zhu] as the Chinese imperial family [the Imperial House of Zhu]. 

This [the Beiyang Goverment being formed as the Empire of China ruled by the Imperial House of Zhu and |the Beiyang Government| never |the Beiyang Government| being |the Beiyang Government| a Republic |the Beiyang Government|] is  [the Beiyang Government being |the Beiyang Government| formed |the Beiyang Government| as the Empire of China ruled by the Imperial House of Zhu and |the Beiyang Government| never |the Beiyang Government| being |the Beiyang Government| a Republic |the Beiyang Government|] due to [why the Beiyang Government is |the Beiyang Government|  formed |the Beiyang Government| as the Empire of China ruled by the Imperial House of Zhu and |the Beiyang Government| never |the Beiyang Government| being |the Beiyang Government| a Republic |the Beiyang Government|] the influence of  the millenianist Chinese folk religious sect focused on militant self-defense and tax resistance along with romanticised monarchism, wishing to restore the pre Qing Han Chinese Imperial House of Zhu-ruled Great Ming State/Great Ming Empire/"Ming dynasty" as the government of China, the Yellow Sand Society, which [the Yellow Sand Society] has [the Yellow Sand Society] been [the Yellow Sand Society] been  [the Yellow Sand Society] gathering strength and influence among the Chinese people, the pervasive influence of the Cantonese-Han Chinese secret societies and organized crime syndicates known as the Triads, which [the Triads] are pervasive through Cantonia [Guangdong and Guangxi] and [the Triads] also have the goal of [the Triads' goal] restoring the the pre Qing Han Chinese Imperial House of Zhu-ruled Great Ming State/Great Ming Empire/"Ming dynasty" as the government of China despite their [the Triads'] criminal activities and also to counter the influence of the charismatic leader of the Xinhai Revolution and subsequent founder of the Han nationalist, Han supremacist, Chinese nationalist, Chinese imperialist, Marxist-Stalinist, semi-fascist political party/militant group/secret society of the KMT/Kuomingtang after the toppling of the Great Qing Empire via the Xinhai Revolution and the subsequent formation of the Beiyang-ruled first ROC as the government of Han China, the Cantonese-Hakka doctor turned Han nationalist revolutionary and stateman Sun Wen, who [Sun Wen] is [Sun Wen] known as [Sun Wen's other name] "Dr. Sun Yat-Sen" outside Asia along with the desire of the Han Chinese people to emulate the Meiji Restoration, as well as Japan taking a more involved and direct role in [Japan] helping to [Japan] covertly support and [Japan] direct the Xinhai Revolution.


Due to Shikai never [what Shikai never does] proclaiming himself [Shikai] as Emperor of Han China and the Chinese monarchy [the Great Ming State and the Imperial House of Zhu] being [the Great Ming State and the Imperial House of Zhu] restored [the Great Ming State and the Imperial House of Zhu] as the government [the Great Ming State and the Imperial House of Zhu] of Han China through the Beiyang Government-ruled Empire of China], [the Great Ming State and the Imperial House of Zhu being |the Great Ming State and the Imperial House of Zhu| restored |the Great Ming State and the Imperial House of Zhu| as the government |the Great Ming State and the Imperial House of Zhu| of Han China] as was the goal of the Xinhai Revolution [restoring the Ming to power in Han China after the overthrow of the Qing], the modern warlord era of post-Xinhai, post-Qing Han Chinese history from 1916 to 1928 never happens due to the vast majority of Han Chinese people supporting the restored monarchy [the Great Ming State and the Imperial House of Zhu] and the reenthroned Chinese imperial family [the Imperial House of Zhu] being [the Imperial House of Zhu] ready [the Imperial House of Zhu] to [the Imperial House of Zhu] listen to the Han Chinese people's needs.



Yuan Shikai still [Shikai] creates an extensive peerage system for the Empire of China but [Shikai] merges it [the Empire of China's peerage system] with [what Shikai merges the Empire of China's peerage system with] the pre-Genghis Khan-descended Mongolian Imperial House of Borjigin-ruled Great Mongol Nation/"Mongol Empire" and its [the Great Mongol Nation's] successor state ruling over much of Siberia, parts of Central Asia, Inner and Outer Manchuria, Han China, Guangdong, Guangxi, Yunnan, East Turkestan and Tibet from Greater Mongolia, the Genghis Khan-descended Mongolian Imperial House of Borjigin-ruled Great Yuan Empire/Great Yuan State/Yuan dynasty, [the pre-Mongol Empire and pre-Yuan dynasty] Han Chinese Imperial House of Zhao-ruled Great Song State/Great Song/Empire of the Great Song/"Song dynasty"  and the pre-Manchu Imperial House of Aisin-Gioro-ruled Manchu-dominated Great Qing Empire/Empire of the Great Qing ruling over Han China, Greater Mongolia, Tuva Guangdong, Guangxi, Yunnan, East Turkestan and Tibet from Inner and Outer Mongolia, Ming era [the pre-Mongol Empire, pre-Great Yuan, and pre-Qing] Han Chinese aristocracy, monarchy and nobility, [Yuan Shikai merging the Empire of China's peerage system with the pre-Mongol Empire and pre-Great Yuan Empire, Song era and pre-Qing Ming era Han Chinese aristocracy, monarchy and nobility] to [Shikai] create a coherent, united aristocratic system of peerage for the country [the Empire of China]. 

 The descendants of the last emperor of the Great Ming State, Zhu Youjian, who [Youjin] had the era name of [Youjin’s era name] Chongzhen, and the last emperor of the Ming rump state of the Southern Ming, Zhu Youlang, whose [Youlang’s] era name was [Youlang’s era name] Yongli being [the descendants of Chongzhen and Yongli] are [the descendants of Chongzhen and Yongli] merged [the descendants of Chongzhen and Yongli] into a single imperial line [the descendants of Chongzhen and Yongli] via multiple marriages, concubinages and adoption, although the marriage of Shikai's daughter to the last Emperor of the Great Qing State, the then young Aisin-Gioro Henry, whose [Henry's] era name was [Henry's era name] Pu-Yi, [the marriage of Shikai's daughter to Henry] as one of his [Henry's] wives continues and goes on despite Shikai never [what Shikai never does] crowning himself [Shikai] Emperor of Han China.

Shikai's reenthroment of the Zhu after the formation of the Empire of China instead of [Shikai] crowing himself [Shikai] Emperor of Han China ironically solidifies his [Shikai's] legacy and [Shikai's reinstatement of the Great Ming State through the Empire of China] also prevents the mass session of provinces from the Beiyang-ruled first ROC due to reformers, modernists and decentralists both in the Kuomingtang and the Beiyang government structure promoting a federal government structure that allows for the autonomy and freedom of the provinces of Han China proper within the boundaries of the Empire of China, akin to that in the German Royal House of Hohenzollern-ruled Kingdom of Prussia-dominated German Empire. 


The American educated Cantonese statesman Tang Shaoyi becomes [Shaoyi] the first Prime Minister [Shaoyi] of the Empire of China from 13 March 1912 to 1915, [Shaoyi] followed by the Roman Catholic priest and monk Lu Zhengxiang  from 1915-1920, followed [Zhengxiang] by Xu Shichang from 1920- 2 June 1922 and then by Wen's chosen successor and heir of his [Wen's] will, Wang Jingwei from 1923-1947, who [Jingwei] presides over a alternate Second Sino-Japanese War pitting the restored Ming, Japan and even Qing-ruled Manchuria against KMT splinter cells lead [the KMT splinter cells] by [the leader of the KMT splinter cells] Wen's other student Chiang Kai Shek, and then [Jingwei being |Jingwei| succeeded as Prime Minister of the Empire of China] by Xu Hanhao of the Han Chinese nationalist, Han Chinese imperialist and Han Chinese expansionist Young China Party from 1948-1952, and then by Li Huang from 1952-1975, also [Huang] of the YCP, then Hua Guofeng from 4 February 1976 – 10 September 1980, who [Guofeng] remained in the YCP due to the Han nationalist, Han supremacist, Han imperialist, Marxist-Stalinist fascist Chinese Communist Party remaining within the YCP, then Hu Jintao from 8 July 1985 to  1 December 1992 who [Jintao] remained in the YCP like Guofeng and the other CCP members, then Ma Ying-jeou of the KMT from 20 May 2008 – 20 May 2016, Eric Chu of the KMT from 20 May 2016 to  13 January 2024 and then finally Wenzhou Wu of the YCP from Febuary 2024, by the modern-era equivalent in this timeline. 


The National Protection War of 25 December 1915 – 14 July 1916 between the Beiyang-ruled first ROC as the Empire of China and what would become  the Han nationalist, Han supremacist, Chinese nationalist, Chinese imperialist, Marxist-Stalinist political party/militant group/secret society of the KMT/Kuomingtang and the joint American-Soviet satellite state the KMT ruled with an iron fist, the Unitary, adhering to Sun Yat Sen's three principles of the people, nationalism, democracy and socialism [social welfare] one-party ruled and dominated directorial republic under a military dictatorship of the Second Republic of China/Nationalist China/National Government of the Republic of China, then [the embyroic Nationalist China] under the rule of Wen/"Yat-Sen" [The National Protection War]  ends with the victory of the Empire of China over the embryonic Nationalist China due to Shikai never making himself [Shikai] Emperor and [Shikai] instead returning the Zhu to power in China, the Empire of China agreeing for Yunnan to [Yunnan] secede [Yunnan] from  the Beiyang-ruled first ROC and [Yunnan] subsequently restore the Bai-Han Chinese Imperial House of Duan-ruled absolute feudal dynastic royal imperial monarchy of the  Daili Kingdom as its [Yunnan's] government in exchange for Yunnanese support against the Chinese nationalists, and Cantonian independence activists and supporters in the Nationalist strongholds of Guangxi and Guangdong undermining the Nationalist war effort. 

A miscommunication between Wen/"Yat-Sen" and his [Wen's] Japanese backers leads to the Japanese switching support from the Nationalists to the Beiyang-ruled ROC as the Empire of China during the National Protection War, although the Japanese do take Manchuria and Inner Mongolia as protectorates, [the Japanese] restoring the Manchurian monarchy [the Imperial House of Aisin-Gioro and the Great Qing Empire] in Manchuria and [the Japanese] reestablishing the Genghis Khan-descended Mongolian Imperial House of Borjigin-ruled Great Yuan Empire/Great Yuan State/Yuan dynasty in Inner Mongolia. 

Wen/"Yat-Sen" is [Wen/"Yat-Sen"] killed [Wen/"Yat-Sen"] during the fighting and the Nationalist Chinese state headquartered in Guangdong and Guangxi essentially becomes a independent Cantonian republic after his [Wen's/"Yat-Sen"'s] death due to Cantonese independence activists and [Cantonese] nationalists desiring a separate state from Han China taking over Nationalist China after his [Wen's/"Yat-Sen"'s] death. 

The Second Sino-Japanese War of 1928-1947 between the Japanese Empire and Nationalist China with both the USA and the USSR backing Nationalist China never happens due to the earlier death of Wen/"Yat-Sen" and the Beiyang Government's Japanophilic, pro-Western leanings. 
Although Kai-Shek does [Kai-Shek] attempt to [Kai-Shek] lead Kuomingtang splinter cells in Nationalist China in rebellion against both  Nationalist China and the Empire of China in the 1920s, the Cantonese people, [the Cantonese people] satisfied with independence from both Han China and Manchuria, [the Cantonese people] are uninterested in his [Kai Shek's] dreams for a Greater Nationalist China having all the territory of the Qing dynasty despite significant support for him [Kai-Shek] from both the USA and the USSR and Kai-Shek finds himself [Kai-Shek] a virtual outcast [Kai-Shek], [Kai-Shek] eventually being [Kai-Shek] assassinated [Kai-Shek] by a Triad assassin when [Kai-Shek] leaving Nationalist China in around 1939-1940.  

The restored Great Qing Empire in Manchuria does transition into the Japanese protectorate of the Qing Imperial family, the Manchu House of Aisin-Gioro-ruled Empire of Manchukuo in Manchuria in a slow process of constitutional reform and governmental development from the late 1920s until the early 1930s and the restored Yuan dynasty in Inner Mongolia does transition into the Japanese protectorate of Genghis Khan-descended Imperial House of Borjigin-ruled Mongolian Autonomous Federation/Mengjiang in Inner Mongolia's Chahar and Suiyan regions. 

The side branch of the Genghis Khan-descended Mongolian Imperial House of Borjigin, the Mongolian Imperial House of Chagatai-ruled joint-Islamic sultanate and Mongolian khanate of the Kumul Khanate in East Turkestan's Hami provinces, [the Kumul Khanate] takes over the rest of East Turkestan and East Turkestan never becomes a part of Han China. 

The theocratic Buddhist absolute monarchy of the Lama-ruled Kingdom of Tibet in Tibet is [the Kingdom of Tibet] never integrated [the Kingdom of Tibet] into China, [the Kingdom of Tibet] remaining independent [the Kingdom of Tibet] to this very day. 

The Beiyang Government is [the Beiyang Government] still  [the Beiyang Government] Japanophilic and  [the Beiyang Government] friendly to the West despite it [the Beiyang Goverment] being [the Beiyang Goverment] a modern incarnation [the Beiyang Government] of the Great Ming State in this scenario, with Japan still having good relationships with and a fair amount of control over the Beiyang Government. Due to the Second Sino-Japanese War never happening, the Beiyang Government, Manchukuo, Mengjiang and Imperial Japan all [the Beiyang Government, Manchukuo, Mengjiang and Imperial Japan] survive [the Beiyang Government, Manchukuo, Mengjiang and Imperial Japan] post-WW2 and post-1947 into the present day and beyond with Nationalist China surviving post-1949 into the present day and beyond.
