Red Cloth Strips and Old Locust Tree

In 1969, Shanghai educated youth Su Minzhi and Chen Jianguo met on the train to Tangwo Village in southern Jiangxi. They fell in love under the old locust tree at the head of the village while jumping in line. After an unexpected pregnancy, the two entrusted their son Tang Xiangyang to their neighbors, using a red cloth strip and a hero pen as a token. After returning to the city, Su Minzhi failed to recognize her for various reasons. Tang Xiangyang went to Shanghai with a token to find his mother seven times but failed, which became a regret in his life. In 1995, Su Minzhi suddenly fell ill and passed away, and her diary revealed the hidden secrets of her spying on her son. Tang Xiangyang untied his heart knot in Chen Jianguo's confession, and inherited family memories with his half-sister Zhou Yutong. The red cloth strips and the old locust tree in Tangwo Village witnessed the bond between three generations.
