Answer:
The period that goes from the fall of the Qing dynasty to the proclamation of the People's Republic of China in 1949 is called the Republic of China, and it was a time of great turbulence and changes known in Chinese history.
In western China many local chiefs declared themselves in rebellion, and in this way Chiang Kai-shek saw himself ruled nominally to China, but in practice he realized that in many parts of the country his power did not exist and he saw prolonged, in the worst possible way, the first stage of which Sun Yat-sen had declared for the Chinese advance: the fight against the enemy was extended, because there were enemies in the house itself. The rest of his government was a continuous struggle and retreat against the opposing forces, Chinese or foreign, until he was expelled to Taiwan in 1949.
