After the Three Kingdoms of Wei, Shu and Wu, what kind of ups and downs did the Han nation experience? There are very few folk tales about this period. After re-reading the history of this period, I found that the lack of romance is not because I am not familiar with it, but because the harm this period of history has brought to the Han nation is too painful. You have to have a good mood when writing stories. The heavy burden makes novelists unable to feel happy and ridiculed. Forgetting history means betrayal. What we need is not just the glory of the Han and Tang Dynasties, but also the historical lessons of those who were enslaved, invaded, plundered and massacred, instead of choosing to escape and forget. "How can the Huns be home until they are destroyed? The imperialists will not die in their desire to destroy themselves." These aphorisms apply to every period of the Chinese nation.
