The abandoned child Gou Sheng (played by Jiang Long) was adopted since childhood. In order to earn money to marry a wife, he joined the army to replace his stupid brother Wang Mao. During his military service, Gou Sheng was framed by his rival Yang San (played by Jiang Yi) from the same village. He also experienced many bizarre and thrilling encounters. Along the way, he met like-minded friends such as Song Yutao (played by Shi Ce). After experiencing the baptism of war, Gou Sheng deeply realized that there would be no small family without a country. He changed from a farmer to a real New Fourth Army soldier, completing his life transformation. The play is adapted from the movie "I'm Not Wang Mao".
