Why do the Japanese have the audacity to say that we created Chinese culture after stealing it?

Japan even steal people over, Japanese people have part of the Chinese blood, so so that Japan not only steal our culture, but also steal our blood. You are talking about the stick dog! This country is really disgusting, stealing our traditional culture and still say loudly that it is their own, compared to the Japanese will also recognize its origin, Japan called kanji never called Japanese characters. Instead of Korean dogs, maybe they will change it to Korean characters.
