Introduction to "Ten Thousand Years of the Emperor": According to folklore, the four characters "Ten Thousand Years of the Emperor" were written in regular script by Wen Tianxiang, the national hero of the Southern Song Dynasty, right prime minister and privy envoy. Wen Tianxiang once led troops from Meixian County to the north to recapture Huichang. When he passed by Han Xianyan, he was worried that the Southern Song Dynasty was in danger, so he wrote these few characters in the hope of turning the tide and continuing the Southern Song Dynasty. Another folk theory is that these four characters were written by the national hero Yue Fei of the Southern Song Dynasty. The basis is that the handwriting is very similar to the handwriting written by Yue Fei in Tianyan, Yuduluo. There is also a couplet on both sides of the big characters, part of which is blurred.
