Collect information on the Nanjing Massacre and talk about how we should face history]

In Yanziji alone, the Japanese army killed hundreds of thousands of people and tens of thousands of Kuomintang soldiers in a beautiful grand canyon. Moreover, when attacking Nanjing, two Japanese officers competed to kill people, which was extremely cruel and sporadic. Nanjing Massacre is a disgrace in the history of our country. We must not forget it. We must remember that once our country is a little weaker, it will be bullied by other countries.
