Paying Homage to Nephew: Changshan Has No One to Return To.

In the fifteenth year of Tianbao, Shi Siming's rebels broke into Changshan and the prefect Yan Gaoqing was captured. In order to protect the rebels' defense plan, his nephew Yan Jiming deliberately captured him and diverted the enemy. Changshan scribe Chen Sheng was entrusted by Chief Shi Feng Qian to flee to Pingyuan County with a secret letter. On the way, he learned the truth about Yan Jiming's hidden map and returned to Changshan to retrieve the defense map despite the danger. After eleven days of hardships, crossing glaciers and deep mountains, he finally delivered the secret message and defense plan to Yan Zhenqing, the prefect of Pingyuan. Later, Chen Sheng returned to Changshan with his team and risked his life to retrieve Yan Jiming's head, which was hung on the top of the city for public display. Yan Zhenqing wrote the "Manuscript of Memorial to My Nephew" with tears in his eyes to pay homage to his brother and nephew and the thousands of people who died for the country. Chen Sheng stayed in the plains and held on as a scribe, carrying the sincerity and expectations of the deceased, guarding the peace in troubled times, fulfilling his original intention of "never break his promise when he promised," and witnessing that the righteousness of his family and country will never be extinguished in blood and fire.
