"Secret Notes from the Zhumen": Lin Wenxiu, a new scholar in the imperial examinations, pays homage to his master, and becomes suspicious when he sees the plaque "Don't talk about state affairs". When he was led into the secret room late at night, he was shocked to see hundreds of unopened letters of allegiance dating back thirty years. The master entrusted him before his death, telling him that one of the letters was related to the fate of the country and involved the secrets of the royal family. When the precarious Ming Dynasty came to an end, these silent letters became the secrets and shackles that Lin Wenxiu had to bear, and also secretly affected the fate of the entire empire.
