This is 272 years later, which means that Wang Mang's head has been collected for more than 270 years! Why is this? Why did the emperor do this? I think there are probably the following reasons.
First, since the Qin Dynasty, there have been 15 emperors in the Qin Dynasty, a total of 17 emperors. Except Qin Ershi, they all committed suicide. So Wang Mang was the first emperor to be beheaded. Drive from this point. Wang Mang's head portrait is of special significance and undoubtedly has collection value.
Secondly, Wang Mang is a controversial emperor. Before he became emperor, his prestige and prestige among the people were very high. He served his mother and widowed sister-in-law, raised his brother's children, was strict in conduct, made friends with wise men abroad, and served uncles at home, which was very thoughtful.
You should know that the nobles in that period were extravagant and dissolute, and Wang Mang was also a nobleman. So he was a moral model at that time. Therefore, Wang Mang was regarded by the ruling and opposition as the only person who could pull the crisis at that time, and was regarded as "the Duke of Zhou was near-re-embodiment".
Third, in the eyes of the emperor, Wang Mang was a traitor and traitor under the typical feudal system. He was a courtier of the Western Han Dynasty, but he ousted his master and replaced him himself. This kind of situation cannot be allowed for future emperors, and it can't happen again. The biography of Wang Mang in Hanshu records that "the ignorant traitors in Hanshu are not as reckless as they are."
