Chinese attitude is fair to the history, Chinese didn't forget Good Japanese like 林弥一郎, also remember those BAD Japanese members like Unit731. To tell our generations if they won't repeat such massacre like 60+ years ago, China need Strong and build a powerful military strength.
That is indeed very true. It cannot be ignored that the Chinese soldiers and civilians practiced 義.
The things that we Japanese will never forget is how Chinese families adopted the thousands of Japanese children who were left abandoned in China. Many were adopted into Chinese families, and grew up and took Chinese identity....truly...仁 and 義.
