December 13 marks the 10th national memorial day and the 86th anniversary of the Nanjing Massacre, which took place in 1937. During the six-week massacre, Japanese invaders brutally killed about 300,000 Chinese civilians and unarmed soldiers.

A memorial ceremony is underway at the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders to remember those killed by Japanese aggressors during World War II. In 2014, China’s top legislature designated December 13 as the national memorial day to keep the darkest history firmly in mind and cherish the hard-won peace. Join CGTN’s special coverage for more.
