The 9.18 Historical Museum in Shenyang, Northeast China's Liaoning Province. The museum was founded to mark the Mukden Incident, or Sept 18 incident in 1931. On that day, Japanese troops destroyed a section of railway in northern Shenyang and attacked a Chinese garrison in the Beidaying area of the city the same night. The incident was the start of the Japanese military occupation of Northeast China, then known as Manchuria, until Japan surrendered in August 1945. [Photo/IC]
