of the Kuomingtang's armed wing and thus the Nationalist Chinese regular Army and combined armed forces, the National Revolutionary Army, [the NRA] subsequently falling into disarray at and after the fall of both Nanning and Chongqing, with many NRA units either turning tail, joining the Peacekeeping Army or becoming bandits with the military intelligence agency of Nationalist China before 1946, devoted to intelligence gathering and covert spying operation for purposes of national security and defense, having great influence amongst the Nationalist Government's  police, administration, and transportation agencies, as well as embassies and consulates abroad along with the National Revolutionary Army, often criticized by the political dissidents as a "secret police" involved in covert and espionage operation, including surveillance, kidnapping, assassinations, elimination and house-arrest against Chinese communists, Japanese spies as well as political dissidents, the Bureau of Investigation and Statistics, [the Bureau of Investigation and Statistics] along with the agency of the cabinet level ministry under the Nationalist Chinese 113 member unilateral legislature whose members are directly elected for four-year terms by the people of Nationalist China through parallel voting which is also responsible  for the passage of legislation in Nationalist China, which is

the Legislative Yuan, responsible for home affairs and security throughout Nationalist China including population, land, construction, military service administration, national emergency services,

branch of the Kuomingtang switch sides to the pro-Japanese Splinter Cell of the Kuomingtang ruling over Republic of China as the Japanese protectorate of the Reorganized National Government of China in Han China, with the five coloured flag of the Beiyang Government and of the first Republic of China flying over both Nanning and Chongqing along with Xibei San Ma's capital of Xining, the Nationalist Chinese National Police Agency and the Bureau of Investigation and Statistics begin helping the Peacekeeping Army and Imperial Japanese Armed Forces, along with the ground combat wing of the Imperial Japanese Armed Forces' military police, with shared espionage, and counter-intelligence roles within the Greater Japanese Empire, Japanese protectorates and Japanese occupied territories during wartime, with its broad duties including maintaining military discipline, enforcing conscription laws, protecting vital military zones, and investigating crimes among soldiers, along with issuing travel permits, recruited labor, arrested resistance, requisitioned food and supplies, spread propaganda, and suppressed anti-Japanese sentiment in Japanese occupied territories, the Kempeitai and the Imperial Japanese Armed Forces' naval warfare branch's Imperial Japanese Navy's military police concerning itself with  police and personnel work within the Imperial Japanese Navy: personnel, discipline and records, having commissar roles in relation to exterior enemies or suspicious persons, watching inside inside units for possible defectors or traitors under the security doctrine of

against the Great Japanese Empire, the Reorganized National Government of the Republic of China, the Empire of Manchukuo, Mengjiang, the Yunnan Clique and the anti-Nationalist Chinese government Chinese warlords.

In the Treaty of Nanking that sees Nationalist China and by extension US and Soviet forces in the China region surrender to the Japanese lead coalition, thus ending the Nationalist Chinese-Soviet-British-USA vs Japan-Manchuria-Inner Mongolia-Beiyang Government as the Reorganized National Government War, Nationalist China is forced to recognize the Reorganized National Government of the Republic of China, the Empire of Manchukuo, Mengjiang and the Yunnan Clique as independent states from Nationalist China and the Reorganized National Government of the Republic of China as the legitimate Chinese state. 

Nationalist China is also forced to give up all claims to Han China, , Inner Mongolia  Yunnan, Inner and Outer Mongolia, Manchuria and Outer Manchuria East Turkestan and Tibet via the Treaty of Nanking in exchange for its continued existence in Guangdong and Guangxi, albiet under Japanese protection. 

Nationalist China becomes the Japanese protectorate of the Cantonese nationalist and Cantonese independence section of the Kuomingtang-ruled,  adhering to Dr. Sun Yat-Sen's three principles of the people, nationalism, democracy and socialism, adhering to the political principle of Dǎngguó Unitary  one-party directorial presidental parliamentary federal republic of the South China Republic, with the then combined Nationalist Chinese of state and simultaneous leader of the NRA during that time period, Chiang Kai Shek's second in command, Li Zongren, becoming the South China Republic's first President with the then Nationalist Chinese chairman, Li Sen being the South China Republic's first Vice-President. 

Thus the Second Sino-Japanese War of 1928-1947 between the main branch of the Kuomingtang-ruled main faction of Nationalist China headquartered in Guangdong and Guangxi, the British Empire, the USA and the USSR and the Great Japanese Empire, the Beiyang Government-ruled first Republic of China as the Reorganized National Government of China in Han China, the Empire of Manchukuo in Manchuria, Mengjiang in Inner Mongolia's Chahar and Suiyan provinces, the Yunnan Clique in Yunnan and the Chinese warlords ends with the victory over the latter over the former in this timeline unlike in real life and becomes this timeline's version of the Vietnam War of 1955-1975 in real life between the fascist Personalist, communitarian, spiritualist Personalist Labor Revolutionary Party-ruled Unitary dominant presidential constitutional republic under a military dictatorship of the Republic of Vietnam in South Vietnam, the Republic of Vietnam's combined armed forces responsible for the defence of the Republic of Vietnam, the Republic of Vietnam Armed Forces, the de jure Marxist-Leninist, anti Stalinist communist Chinese nationalist, Han supremacist, Han nationalist Chinese Communist Party-ruled de jure Socialist Republic but de facto one party dominant presidential federal republic under a totalitarian military dictatorship of the People's Republic of China ruling over Han China, Guangdong, Inner Mongolia Guangxi, Yunnan, East Turkestan and Tibet from Manchuria and Shanxi since 1949, more specifically the CCP's armed wing and thus the PRC's combined armed forces, the People's Liberation Army, the unitary presidental Republic of the Republic of Korea in South Korea and the Republic of Korea's combined armed forces, the Republic of Korea Armed Forces against the Marxist-Stalinist, communist, Vietnamese Nationalist Communist Party of Vietnam-ruled socialist Republic of Socialist Republic of Vietnam in North Vietnam, the Communist Party of Vietnam's armed wing and thus the Socialist Republic of Vietnam's combined armed forces, the People's Army of Vietnam, the post-WW2 Soviet armed forces, the Soviet Armed Forces and the post-WW2 Soviet military service with foreign intelligence, domestic secret police within the USSR and concentration camp duties known as the KGB.

The Japanese revert the Beiyang Government-ruled of the first Republic of China back from the Reorganized National Government of the Republic of China to a modernized, contemporary version of the Beiyang Government-ruled first Republic of China's short lived stint as the unitary parliamentary constitutional Imperial Royal monarchy of the Empire of China formed by Yuan Shikai in 1915 but this timeline with the descendants of the Imperial House of Zhu being renthroned as the Empire of China's reigning Imperial family instead of Yuan Shikai's descendants being formally enthroned as the latest reigning imperial family of China after the Second Sino-Japanese War in this timeline, although the reforms and improvements to the governance and administrative structures of the Beiyang Government-ruled first Republic of China in Han China as the Reorganized National Government of the Republic of China in Han China are kept when the Beiyang Government-ruled first Republic of China transitions from the Reorganized National Government of the Republic of China in Han China back to the Empire of China formed and lead by Yuan Shikai, albiet with the Zhu descendants as the current reigning Chinese imperial family instead of Yuan Shikai's descendants being formally enthroned as the latest reigning imperial family of China.

The Japanese also transition the Yunnan Clique to an independent Yunnanese state before restoring the Daili Kingdom and the Daili Kingdom's reigning combined royal and imperial family, the Imperial House of Duan to power in Yunnan through the Yunnan Clique.
