Daming: Let You Guard Haimen and You Will Continue the Destiny of the Country.

In the thirty-fourth year of Jiajing's reign, the Japanese invasion of Southeast China was becoming serious. Shen Huaishan, a veteran of coastal defense, was falsely accused of treason with the Japanese and died in prison. His son Shen Yan was scolded by his tribe as a "Japanese traitor" and his family property was taken away. His sister was almost sold to a salt merchant as a concubine, and was even sent to the most dangerous place of Haimen Dun to keep vigil with a military post. Everyone thought that he would not survive more than three days, but Shen Yan relied on half of the "Coastal Defense Notes" left by his father to read the tides, identify the reef routes, check the account books, and light the beacon fire. Starting from seven old and weak soldiers, he guarded the village, rescued his sister, killed Japanese pirates, broke the secret accounts of salt merchants, and checked the empty pay of the guard station. Others asked him to guard Haimen until death, but he guarded a broken beacon pier as the first flag of southeastern coastal defense. Many years later, Japanese pirates, wealthy businessmen, corrupt officials, strict party officials, and chronic abuses in border towns came one after another, and the national destiny of the Ming Dynasty was on the verge of collapse. Shen Yan looked back at the original Haimen pier and said only: "The holes are mended one by one, and the national destiny continues day by day."
