The retired veteran was injured for saving Dana's father in the war, and the shrapnel in his brain caused him to suffer from intermittent amnesia. In order to repay his gratitude, Dana asked his son to take the veteran back to live with him, but the old man was lost due to Mu Sheng's negligence. All the villagers of Xiangyashan finally found the old man. In order to praise everyone's virtue of being helpful and helping each other, the village established the Xiangyashan Assistant Group and awarded everyone the title of "Good People of Xiangyashan". The old man returned to the war years with disordered memories. The villagers acted with him to help him regain his memory, and also found his comrades who had lost contact for many years, so that the old man could fulfill his wish. In this process, everyone empathized with the entire military career from joining the army to resisting the United States and aiding Korea. Everyone grew up differently as if they had been a soldier. At the same time, it also made everyone realize that without the bloody battles of the revolutionary predecessors, there would be no peaceful era today. Let us learn to cherish today's hard-won happy life and learn to be grateful.
