China and Japan have a very long history since ancient times, as early as the fourth year of the Tang Dynasty (630), Japan sent Tang envoys to the Tang Dynasty, bringing China's advanced cultural system, science and technology back to Japan, which has a huge impact on Japan, which is in a period of change.
After the Meiji Restoration, Japan embarked on the capitalist road, they mastered new technologies, industrialized the country, greatly increased productivity, greatly improved economic capabilities, and became one of the world's economic and military powers. But Japan is an island nation with extremely few resources, so they set their sights on China.
After the Sino-Japanese Sino-Japanese War, Japan ate the sweetness of the Qing Dynasty, so it began to constantly think of ways to launch a war of aggression against China. On September 18, 1931, the Japanese army blew up the South Manchuria Railway tracks near Shenyang's Wicker Lake, planted stolen goods for the Chinese army, and used this as an excuse to launch the "918" Incident, and then invaded and occupied the three northeastern provinces.
After the Japanese army invaded and occupied the three northeastern provinces, it did not give up but extended the magic grip to Shanghai and North China, constantly provoking incidents. Until July 7, 1937, the "July 7 Incident" was brazenly launched, and from the 16th onwards, 5 divisions and regiments were recruited to China, boasting of haikou such as "three months to destroy China".
At a time when the nation was living and dying, the people of the whole country rose up to resist Japan. Although the Japanese army made rapid progress in the beginning, as the tug-of-war unfolded, the Japanese army began to become difficult until it was difficult to move. However, most of China was still occupied by the Japanese army, and only 8 provinces never fell.
First of all, some provinces are not completely subjugated, but are in a state of partial captivity, these provinces are. Henan Province (98.5% fall), Shanxi Province (98.2% fall), Anhui Province (81.9% fall), Zhejiang Province (78.6% fall), Suiyuan Province (71% fall), Guangdong Province (70.3% fall), Guangdong Province (70.3% fall), Hubei Province (69.3% fall), Guangxi Province (68.6% fall), Hunan Province (68.4% fall), Jiangxi Province (63.5% fall), Fujian Province (18.5% fall), Guizhou Province (4.8% fall), Yunnan Province (3.3% fell).
In addition, there are 8 provinces that have not fallen at all, and these eight provinces are Xinjiang, Shaanxi, Gansu, Ningxia, Tibet, Sichuan, Qinghai, and Xikang. Many people may not have heard of Xikang, right? So where did this province end up?
The answer is to merge, Xikang Province was first set up in the 28th year of the Republic of China (1939), the jurisdiction of the place is roughly equivalent to the current Sichuan Ganzi Tibetan Autonomous Prefecture, Ya'an City, Aba Tibetan and Qiang Autonomous Prefecture, Eastern Tibet Chang and other areas, the reason why this provincial capital was set up in that year is to better manage the rear area, Xikang Province as the main traffic route into Tibet in the interior, at that time had important strategic significance.
After the founding of New China, that is, in 1955, Xikang Province was abolished again, and its jurisdiction was divided into two surrounding provinces. It's been 65 years since it was revoked, so it's normal that many people haven't heard of it.
