As a rising star among various film categories in China, animated films hold a pivotal position. Directly targeting a vast audience of children and teenagers, they enjoy a natural advantage in cultural dissemination and ideological guidance. Since the creation of China’s first animated film, The Big Stir in the Studio in 1926, a distinctive national style has been one of the most prominent hallmarks of domestic animation. With the integration of modern artistic concepts and advanced animation production technologies, Chinese animation has, after a rich developmental journey, ultimately formed its unique creative paradigm and aesthetic philosophy. As a “young” art form, animation employs a wide array of content expression methods, encompassing artistic forms such as ink wash painting, sculpture, watercolor, and oil painting. Its “all-encompassing” nature also determines that animation art possesses a strong “moldability,” making it more susceptible to the influence of various cultural trends during the creation process. This is particularly evident in the evolution of character design influenced by aesthetic preferences in different periods since the founding of New China. This article will delve into the transformation of public aesthetics since the establishment of New China by examining the artistic expression and gender body structures in characters from domestic animated films. It aims to contribute to the development of China’s animation industry and promote outstanding Chinese culture.
