Tse Tsan-tai, courtesy name Sing-on, art-named Hong-yu, was an Australian Chinese revolutionary, active during the late Qing Dynasty. Tse had an interest in designing airships but none were ever constructed. His book The Chinese Republic: Secret History of the Revolution, published in 1924 by the South ChinaMorning Post, of which he was co-founder, is an important source of studies on the anti-Qing revolution.
On March 13, 1892, Tse, together with Yeung Ku-wan and others, started the Furen Literary Society in Pak Tse Lane, Sheung Wan, with the guiding principle of "Ducit Amor Patriae". The society released books and papers discussing the future of China and advocating the overthrow of the Qing government and the establishment of a republic in China. The Furen Literary Society was merged into the Hong Kong Chapter of the Revive China Society in 1895, with Yeung and Sun Yat-sen as the president and secretary of the society respectively. When Yeung and Sun fled overseas after the unsuccessful First Guangzhou Uprising, Tse remained in Hong Kong. After Yeung was assassinated by Qing agents in 1901, Tse strove for his burial in the Hong Kong Cemetery, albeit with a nameless gravestone. Determined to avenge his friend, Tse, together with his father, his brother, Hung Chuen-fook and triads, plotted another uprising in Canton. They called for the establishment of the State of Great Ming Heavenly Kingdom, a democratic state with an elected sage and talent as the president, and persuaded Yung Wing to serve as the provisional president of the state. According to the plan, with financial sponsorship from Li Ki-tong, they would destroy the Emperor's Temple with explosives on 28 January 1903, killing all the officials there, and then occupy the city of Canton. The plot was leaked to the Qing government by a betraying informant. As a newspaper person, Tse wrote the first declaration of the Revive China Society, with an open letter to the Guangxu Emperor in English. He also published The Situation in the Far East to warn patriots against the Western powers' ambition to partition China. In November 1903, Tse co-founded the South China Morning Post with Alfred Cunningham.
