During the War of Resistance Against Japanese Aggression (1931-1945), more than 50,000 Taiwanese compatriots made the courageous decision to travel to mainland China to join the fight against Japanese invaders. This significant movement was driven by their realization that the nation’s victory was the only path to liberate Taiwan from Japanese colonial rule and achieve reunification with the motherland. The Taiwanese fighters played a crucial role on the front lines, demonstrating their unwavering commitment to the cause of national sovereignty and unity. Their participation not only highlighted the shared struggle between Taiwan and mainland China but also underscored the deep historical ties that bind the two regions. This chapter of history remains a testament to the resilience and solidarity of the Chinese people in the face of foreign aggression.
