Commentators always regarded Chiang Wei-shui as a follower of Dr. Sun Yat-sen’s ideology, one who as opposed to class struggle which undermines national unity, and yet was not against the principle of equality of the socialist. When Taiwanese People’s Party was founded in 1927, the principal theory of the party by Chiang was based on Dr. Sun Yat-sen’s ideology. Back at the time Chiang’s ideas somewhat reflected Marxist ideology, but he remained essentially Sun’s disciple. By 1930, however, Chiang began to be inspired by the “Third Stage of Capitalism” by the Communism International and was influenced by the Great Depression that swept the world. As a result, he renounced his claims that capitalism is in an “ultimate stage” and instead responded to the call of the Communism International. Since then, Chiang has been committed to promoting the proletarian movement. Therefore, from 1930 onwards, Chiang Wei-shui longed for the Soviet Union’s New economic policy on the one hand, thinking that Sun’s ideas demonstrate the possibility of developing into dictatorship of proletariat, and on the other hand, he aspired to integrate with Taiwan Communist Party and Taiwan Culture Association. This leaves much room for discussion as to whether or not Chiang was still a disciple of Sun. The author argues that, at the point Chiang’s leftist attitude was already quite clear. He no longer adhered to the original reformist route, but turned instead to the radical class struggle. The author does not intend to comment on whether Chiang’s timing of the revolution was appropriate or not, but back at the time Chiang felt a glimpse of hope for the liberation of Taiwan and chose to take a chance. Regrettably, things did not turn out the way he expected, but his efforts were still commendable.
