Did someone know anything about the Nanjing Massacre in China?

 the Battle of Nanjing in the Second Sino-Japanese War. Began on December 13, 1937, these  

Japanese war crimes lasted for six weeks, while the first three weeks were more intense.  

This is the most recent mass-scale war crimes in Nanjing since the 1864 Battle of Nanjing.

Although the massacre is generally described as having occurred over a six-week period after  

the fall of Nanjing, the crimes committed by the Japanese army were not limited to that  

period. Many atrocities were reported to have been committed as the Japanese army advanced  

from Shanghai to Nanjing.
