1. Lin Zexu Humen Smoke: His greatest achievement is that he led a vigorous anti-smoking movement in the history of China-Humen destroyed opium, commanded the anti-British struggle, safeguarded national sovereignty and national dignity, and became the first national hero and patriot in the modern history of China. At the same time, he compiled foreign books and materials such as The Chronicles of Four Continents, which initiated the atmosphere of learning and studying the West in modern China and was the pioneer of China's modern reform thought.

2. Sun Yat-sen's Revolution of 1911: Sun Yat-sen really advocated the modern Republican revolution, successfully organized various anti-Qing forces with complex components, and injected elements of modern western political theory and constitutional thought. Although Sun Yat-sen also attached importance to mastering the power of leaders, he was more idealistic and could give up political resources for the needs of system construction. Although Sun Yat-sen advocated overthrowing the autocratic monarchy by force and pacifying the warlord regime by force, his method was mild, the measures of rehabilitation were tolerant, and he did not take the practice of thorough eradication, which was different from that of Chiang Kai-shek or Mao Zedong who emphasized organizational discipline and severely punished opponents.

Sun Yat-sen is also an important stage figure in China's political and economic modernization. Sun Yat-sen comprehensively integrated the important elements of modern western bourgeois democratic thought, including constitutional democracy, people's sovereignty (election, recall, creation, referendum), separation of powers, socialism and so on. In addition, China's traditional institutional institutions-supervision power and review power, which he personally considered necessary, formed the five-power constitutional theory. The popularization of western important thoughts in China has the role of promoter, which has promoted the westernized Democrats and communists to explore the future construction of China. However, Sun Yat-sen took a compromise position in it, but it still has its value to adhere to the constitutional system of republicanism and democracy.
