As a Chinese, we should have a more detailed understanding of this history. Vision not only has a sense of impact, but also makes people feel outraged physically and mentally. There is also a comforting side, many parents with children, patiently and earnestly tell this history, in fact, we do not let children remember hatred, but let them understand that peace needs to be maintained, our life is not easy to come, for this reason, do not forget the national shame, strive to be strong, only in this way, can we let history not repeat, the country no longer fall. I hope that every visitor will go away with respect for the deceased and history, and will not want to see the people who are gagging at the same time.
