Japan invaded northeast China in September 1931. However, historians agree that Japan's full-scale invasion began on July 7, 1937, when the bridge, a crucial access point to Beijing, was attacked by the Japanese.

The exhibition, "Great Victory, Historic Contribution", is also part of events in the run up to the 70th anniversary of the victory of the world anti-Fascist war, which will culminate in a parade on Sept. 3 in Beijing.

Liu said the exhibition showcased brave resistance in the face of invasion and the CPC's role as a corner stone in that endeavor.

Tremendous sacrifices were made by the Chinese people and the exhibition serves as a reminder that China was the major oriental battlefield in WWII, Liu said.
