A bell-ringing ceremony was held on September 18 to mark the 90th anniversary of the "September 18 Incident" at the September 18 Incident History Museum in Shenyang City, northeast China's Liaoning Province.

It was on this fateful day in 1931 that Japanese troops blew up a section of the railway near Shenyang under their control and accused Chinese troops of sabotage as a pretext for subsequent aggression.
