Five flowers, the beginning of the demise of pure Han nationality in China, is a precursor to the decline of China culture. The horror at that time can be said to be more terrible than today's world war. At that time, people, especially women, were not qualified as human beings. They were either slaughtered and eaten as animals at will, or chopped off their feet after being trampled and cooked in a pot. Its horror is still shocking today. At that time, due to the decline of the imperial court, the chaos of the vassal States led to the great loss of the Central Plains. Ethnic minorities in northwest China and Mongolia Plateau took the opportunity to invade the south, and eventually fought with each other, resulting in vendettas among ethnic groups, which eventually led to a heinous case of genocide. I don't want to elaborate on the tragic situation of several ethnic minorities. Its historical significance can only be said that we can learn to cherish the present democratic society, learn to care about others, learn to tolerate others, and don't think that we are always right and others are always wrong. You can also think about it when others don't treat you like a person. We should cherish the present society, don't always think about what is unfair to us, we should safeguard justice, we should safeguard the spirit of justice of all mankind, and we should dare to stop bad things that will happen when we see them, so as to avoid all kinds of unfair things in society.
