-The Lament of Autumn--In the finale, although Ye Pingjun and his son Xiao Yuer finally returned to Yu Changxuan, their reunion failed to stop the war.Yu Changxuan decided to lead the Ninth Army to meet the enemy. Ye Pingjun understood his choice and agreed to wait for his return with his children.Before leaving, the two made an appointment to plant maple trees and watch the trees grow with their children.

Yu Zhongquan originally wanted to preserve his strength, but after reading Yu Mingxuan's diary, he changed his mind and decided to go to the front line with his son.Yu Changxuan met Xiao Beichen at the military camp and learned that his sister Yu Qixuan had been saving people in the field hospital.She had devoted herself to taking care of the seriously injured Xiao Beichen, and asked him to tell her brother that she was also fighting against the enemy and had not brought shame to the family.

Zhao Baoru dismissed her servants and donated gold to support the front line. She originally evacuated with her family, but on the way, she heard that the Japanese had captured the Yu family servants and tried to use them to find Mrs. Yu.She wrote a letter asking Ye Pingjun to take her children on board the ship immediately and return to the Yu Mansion herself, in exchange for the servant's release in exchange for staying.After everyone escaped, she pretended to agree to a contract to surrender, and proposed to go to the ancestral hall to worship her ancestors. She took the opportunity to shoot Gao Qiao, and then sealed the ancestral hall with the housekeeper and lit a fire.

The front line was under continuous bombardment. Yu Zhongquan ordered his son to return to the base camp to support him, while he stayed to hold the position.Yu Changxuan knew that his father was ready to die, so he could only salute with tears in his eyes.Yu Zhongquan finally told his son in person that he had always been his pride since he was a child.

Gu Ruitong, Li Boren and Yu Changxuan continued to fight bloody battles.Yu Changxuan fell under the gunfire, and Ye Pingjun's figure seemed to flash before his eyes.He reached out to grab the hairpin not far away, but in the end his hand dropped weakly, failing to fulfill his promise to reunite with his wife and children.

A year later, Ye Pingjun took Xiao Yu'er to live in the Soviet area, and together with Jun Minru and others, sewed clothes for the soldiers. Liang Wenbo and Song Hanzhi also continued to work there.She took her son to plant a maple tree and hung it with a peace charm, still hoping that Yu Changxuan would come back when the maple leaves turned red.
