was here really hatred between Chinese and Japanses as shown in dramas and movies?

as seems to be really played out in various movies and shows from say around early to mid 20 century, as real hatred between the 2 cultures and peoples?

Thanks does seem to be real hatred between various asian peoples and cultures simmering beneath the surface at times

Japan occupied multiple (mostly East) Asian countries during the end of the 19th century and into the 20th century. Depending on who you ask, there is still lingering resentment and anger. 

Thought your bane was that fat deluded mentally deranged N Korean dictator though
