On December 25, 1945, the formal surrender of Japanese forces in Taiwan took place in what is now the Sun Yat-sen Hall in Taipei, finally bringing to and end 51 years of Japanese rule. This is the Retrocession Day everyone knows about.
一九四五年十月廿五日上午十點，二次大戰中國戰區台灣省受降典禮，在當時的台北公會堂（今中山堂）舉行。台灣於是結束了日本帝國主義五十一年的殖民統治，這是大家知之甚詳的台灣光復節。
