This film is based on the civilian heroes who ferried the People's Liberation Army across the river during the major historical event known as the "Crossing the Yangtze Campaign." Through the ordinary yet extraordinary life experiences of "Bianzi Guniang" (Pigtailed Girl), it skillfully weaves together the important historical chapters since the founding of New China. The film vividly showcases the transformative changes the country has undergone since its establishment, particularly since the 18th National Congress. It allows the younger generation to personally experience the great leap—led by the Party—of the Chinese people standing up, growing prosperous, and becoming strong. The film aims to instill in them a deep love for the Party and the motherland, inspiring them to shoulder the mission of national rejuvenation in the future.
