Unlike China in the May Fourth era, Taiwan today does not face a military threat from Japan or the West. On the contrary, the greatest threat to its survival comes from the mainland communist regime, with which the people of Taiwan share a common Chinese ancestry. But May Fourth patriotism has always been directed outwards, so talking about May Fourth in this very different situation jars badly.
相對五四，今天台灣並未受東洋或西洋軍事上的威脅，反而同一血脈的中共政權給台灣帶來最迫切的生存危機，與五四愛國主義的口徑一致對外全然不同，談五四變得很不搭調。
