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 with a portion of the Bureau of Investigation and Statistics who had spotted him [Keding] talking to Kenji and [the Bureau of Investigation and Statistics agents] tried to kill him [Keding] as a Hanjian [race traitor to the Han Chinese race], but Keding escaped to safety due to IJA officers and operatives of the Imperial Japanese Army’s post-1881, pre-1947 military police with shared civilian secret police, 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 operating in Beijing fighting off the Bureau of Investigation and Statistics agents and [Keding] reluctantly accepted Kenji's offer on the suggestion of his [Keding's] sworn brother, Jingwei the next day, with Keding becoming the next Emperor of the Empire of China after Shikai being approved by the Beiyang Government as the Reorganized National [Beiyang] Government's National Assembly in Beijing, now divided into the Reorganized National [Beiyang] Government's supreme national ruling body of  the Central Political Committee under which was the National Government Committee along with the Beiyang Government as the Reorganized National Government's own version of the Nationalist Chinese Legislative Yuan and the Beiyang Government as the Reorganized National Government's own version of the Nationalist Chinese executive branch which is headed by the Nationalist Chinese Premier and includes its Vice Premier, twelve cabinet ministers, various chairpersons of commissions, and five to nine ministers without portfolio, who are all appointed by the Nationalist Chinese Chairman of the Nationalist Chinese government on the recommendation of the Nationalist Chinese Premier, the Executive Yuan, [Keding succeeding Shikai as the Emperor of the Empire of China being approved by the Reorganized Nationalist Government's the Central Political Committee, Legislative Yuan and Executive Yuan], [Keding] being coronated as the Yuntai Emperor of Han China the next year, 1938 with Jingwei as his Prime Minister, undermining Kai-Shek's claim for legitimacy as the ruler of China as Jingwei begins implementing reforms and restructuring of the Beiyang Government as the Reorganized National Government, implementing land reform, breaking the power of the landlords in Han China and trying his best to fulfill his duties as Dr. Sun Yat-sen’s legitimate heir, along with having the Reorganized National Government engage in diplomatic and trade negotiations with the rest of the world, diminishing the Nationalist Chinese Government's credibility in the rest of the world as Jingwei begins to appear more and more reasonable in the eyes of Axis and Allied leaders in Europe with only Stalin, FDR and their respectivr brainwashed sheep in the USA and Russia supporting Kai-shek, while Kai-Shek's true status as a joint American-Soviet puppet dictator becomes apparent to the world, as the NRA begins to take more and more losses and news of the atrocities being commited by both the NRA and the Bureau of Investigation and Statistics against the people of Guangdong and Guangxi and the residents of the areas of Han China occupied by Nationalist China begin to reach the Soviet and American public, and the American and Soviet anti-Japanese and pro-Kai-shek propaganda just isn't cutting it anymore, while the Yuntai Emperor helps reform the Beiyang Government's post-1912, pre-1928 armed wing and thus the first Republic of China's and the Empire of China's sharedde-facto combined armed forces formed from units of the New Army in the fifteen provinces of Han after the Xinhai Revolution, the large, Western-style Imperial Chinese Army of the Beiyang Army, from both NRA units in the fifteen provinces of Han in the China region excluding Yunnan, Guangdong and Guangxi and former Beiyang Army units that had been demobilised following the Northern Expedition along with fresh recruits, as the Reorganized National Government's post-1940, pre-1945 armed wing and thus its de-facto armed forces, the Peacekeeping Army/Peacebuilding Army, reviving Ming-era and Song-era traditional Han Chinese traditions and culture that had been suppressed under the Great Qing Empire and the Mongol Empire while reviving the traditional Han Chinese dress that had been suppressed by both the Great Qing Empire and the Mongol Empire, Hanfu, gaining the support of the Han Chinese people as defections from the NRA to the Peacekeeping Army/Peacebuilding Army start happening on a daily basis and the agency of the cabinet level ministry under the Nationalist Chinese Legislative Yuan, responsible for home affairs and security throughout Nationalist China including population, land, construction, military service administration, national emergency services, local administration systems, law enforcement, the Nationalist Chinese Ministry of the Interior, overseeing all police forces in Nationalist China on a national level, the Nationalist Chinese National Police Agency, [the Nationalist Chinese National Police Agency] practically coming under the control of the Reorganized National Government along with a section of the Bureau of Investigation and Statistics, which allows the Peacekeeping Army/Peacebuilding Army along with the IJA to push into the Nationalist Chinese provisional capital of Chongqing and Nationalist China's defacto capital of Guangxi's capital Nanning and force Nationalist China to capitulate, bringing Nationalist China's occupied Han Chinese territories under the Reorganized National Government's control and pushing Nationalist China back to Guangdong and Guangxi, where it [Nationalist China] becomes a independent Cantonese nationalist Republic under the control of the remnants of  the post-1912, pre-1924, Cantonese independence, Cantonese nationalist, anti-Chinese unification, anti-Sun Yat-sen and thus anti-Chiang Kai-shek Nationalist Chinese government faction/Chinese warlord clique/Chinese military junta of the Old Guangxi Clique, which [the Old Guangxi Clique] Yat-sen had defeated to [Yat-Sen] gain control over Nationalist China, [Nationalist China becoming an independent Cantonese Republic] with Kai-shek's second in command and de-facto leader of the NRA, the Cantonese warlord Li Zongren succeeding Kai-shek as Chairman of the Nationalist Government while Han Chinese politician Lin Sen remains Nationalist Chinese Premier, albiet as a Japanese protectorate informally known as the Third Guangxi Clique, but now officially known as the Republic of Canton and allowing Japan to win not only the Second Sino-Japanese War, but the Greater East Asian War quickly? 
The Reorganized National Government has the name of the Reorganized National [Beiyang] Government of the Empire of China in Traditional Chinese but the name of the Reorganized National Government of the Republic of China in English, just as how Yuan Shikai's Empire of China had the name "Empire of China/Chinese Empire" in Traditional Chinese but the name "Republic of China" in English.
What would China's name be in both Traditional Chinese with Romanization and English translations, what would its governance style and governing ideology along with its quality of life be like and what would its relationships with Manchukuo, Mengjiang, the Republic of Cantonia, be like? 
And since the Empire of Great Vietnam was essentially a revival/restoration/reconstruction of the Ming dynasty's post-1644, pre-1662 rump state primarily based in Southern Han China and Guangdong and Guangxi, the Southern Ming, what would relations between the Empire of Great Vietnam and China be like?
