Introduction to the portrait of Sun Yat-sen: Sun Yat-sen (1866-1925), famous for his writings, named Rixin, also known as Yixian, was named Emperor Xiang when he was young, and his pseudonym was Zhongshan. Born into a peasant family in Cuiheng Village, Xiangshan County, Guangdong Province (i.e. Zhongshan City), his ancestral home is Shangsha Village, Dongguan County, Guangdong Province. In his youth, he was influenced by the struggle tradition of the Guangdong people and yearned for the revolutionary cause of the Taiping Heavenly Kingdom. He is the pioneer of China's modern democratic revolution, the founder of the Republic of China and the Chinese Kuomintang, and the advocate of the Three People's Principles. For the first time, he raised the banner of complete anti-feudalism, "starting a republic and ending two thousand years of monarchy."
