Why do China people hate the Japanese?

On the one hand, this hatred comes from Japanese aggression against China in history. When we inherit this period of history, we will naturally feel a kind of grief and indignation at the persecution suffered by our compatriots in the motherland, so sometimes this hatred is not deliberately imposed on us by our elders, but a feeling we perceive ourselves. On the other hand, the Japanese are still eyeing around China and doing evil. Japan is against us in the past and now, so this hatred exists in the past and now. Therefore, the older generation has not passed on hatred, and we will still hate Japan through a series of phenomena.
