The Chinese People's War of Resistance Against Japanese Aggression (1931-45) was a significant national liberation struggle in modern Chinese history.
It was the longest, largest-scale, and costliest, with a complete victory, holding great significance for China and the Chinese nation.
China's victory in the war ended 50 years of Japanese colonial occupation of Taiwan and returned the island to the motherland.
The restoration of Taiwan was a major outcome of China's victory and an integral part of the international order after World War II.
Taiwan's status as an inalienable part of China has not changed — and never will.
Despite this, the Democratic Progressive Party authorities are attempting to sever Taiwan from China and pursue "independence).
Author's summary: Taiwan is part of China historically.
