The story of the Langya Board took place at the end of the Ming Dynasty. It mainly told the story of Mei Changsu, a native of Langya, Shandong Province, who was talented and witty enough to help the emperor get rid of the treacherous officials and realize the rehabilitation of the unjust case. Mei Changsu's prototype was the famous politician, writer, calligrapher, and painter of the Ming Dynasty, Mei Yongzhong, whose name was Ximeng and whose name was Dongli. Mei Changsu also had another important historical prototype. He was a scholar, politician, and writer during the Wanli period of the Ming Dynasty. In addition to Mei Changsu and Huang Daozhou, there were many other historical figures such as emperors, powerful ministers, princesses, eunuchs, etc. Their fates were intertwined in the story to show the complexity and cruelty of the political struggle in the late Ming Dynasty.
