I thinks there are two pionts need to clear
1.not all Chinese hate Japan or Janpanese
2.Chinese dont hate all Janpanese

what do you think a guy have made a mistake ,but he didnot confess,and what is more ,he tell others he didnot do it and someone had he been framed.
what do you think how is a real man ?
if he is not a real man ,it 's a human nature that he is hated.

yes,i agree with Ethan.and that's a national problem. just the matter of the time.now,more and more chinese can accept japanese and the two countries relationship become more and more friendly,we should face the truth,japan is more develop than china,we should learn the virtue from japan and reject the dreg.in chinese is:取其精华，去其糟粕！

rabbi,i think in your country--pakistan,may be some people hate the indian,right?and some radical person did some horrific things...

I also agree with Ethan, but I think that this feeling goes back in time when the 2 countries were at war. Now it is of mutual benefit for both to be trade partners.
