The Republican China is a nation in East Asia.
Throughout some of it's history (beginning in 1912) China went under a huge Civil War against the different Chinese (Mandarin, Cantonese, others) and not only that, around 1920s they also had to deal with Communist Chinese as well. With being so torn apart and broken apart by civil war, the Kuomintang started to lose all hope and didn't know what to do. Chiang Kai-shek turned to Empire of Gensokyo (Japan) for help, as they were the Kuomintang's only hope for support and survival. By 1931, Koishi Komeiji ordered the Empire of Gensokyo to invade China. Most of the other Chinese Warlords were distracted and declared war against Gensokyo. However, Koishi Komeiji also secretly helped the Kuomintang to reunite China, and decided that declaring total war against China was bad and strongly discouraged by her friends. The establishment of Manchukuo and Mengjiang was temporary and became Kuomintang strongholds. By 1935 China and Mongolia was conquered, and thus the Kuomintang ruled over China again, though Gensokyo was the actual ruler of China until after the Second World War.
After the war, Chiang Kai-shek held a party for the Chinese Republican Leaders and played Trance and House Music for a week. Meanwhile, Mao Zedong and the remaining Communist Chinese fled to Australia, because of a travel agency recommended it the best place for exile.
After Chiang Kai-shek died in 1975, Ma Ying-jeou became President in 1976. During his rule he upgraded the Chinese Economy to Version 8.0, making it rank in the top 5 at 5th place. Soon in 1996, Ma Ying-jeou was elected Prime Minister instead. Also in 1996, a Chinese Lady, who cosplays Tenshi Hinanawi, was elected as Prime Minister. Speaking of which, at another point, another Chinese Lady who cosplayed as the same character was President of China around the 1950s...
