108 years ago today, on August 25, 1917 (July 8, 1917 in the lunar calendar), Sun Yat-sen led the Law Protection Movement. Tang Jiyao electrified Law Protection On August 25, 1917, Sun Yat-sen summoned some members of the former National Assembly to a meeting in Guangzhou and proposed "Law Protection", that is, to maintain the provisional treaty of the Republic of China. Due to the insufficient number of people attending the meeting, it was called "Extraordinary Congress". The meeting decided to establish a military government in Guangzhou, with Sun as the grand marshal of the military government, Tang Jiyao and Lu Rongting as the marshals.
