The Marco Polo Bridge Incident, or the July 7 Incident in 1937, marks Japan's full-scale invasion of China and the start of the Chinese People's War of Resistance Against Japanese Aggression (1937-1945). The ultimate victory was won by all Chinese people, and should be jointly commemorated on both sides of the Straits after seven decades.

However, it is noteworthy that some are trying to defame the fight behind enemy lines that was led by the Communist Party of China, showing little respect to the wartime history and an unnecessary obsession with the number of battlefield casualties. Similar unwise voices can also be heard in Taiwan, where a few are sought to discourage Kuomintang veterans from attending the commemorative parade on Sept 3 in Beijing, for the sake of their "health".

The hard-won triumph of the Chinese People's War of Resistance Against Japanese Aggression was the first overall victory against outside invasion in China's modern history. The anti-Japanese united national front based on cooperation between the then ruling KMT and the CPC, played a central role in winning the struggle.
