"Unity of Sincerity" was written by Zhu Shilin and directed and animated by the Wan brothers. Produced by Lianhua Film Company in 1932, the film opens with a scene showing a sinister soft-bodied worm gnawing at the northeastern corner of a mulberry leaf. The worm's head is labeled "Japanese Imperialism," while the mulberry leaf bears the words "Republic of China." A group of Chinese people dressed in various ethnic costumes rush to the northeastern corner of the leaf carrying shovels and baskets of soil. Working together, they fill in the gnawed-away section with earth. Throughout this sequence, the slogan "Unity of Sincerity" appears repeatedly on screen. Both "Compatriots, Awaken Quickly" and "Unity of Sincerity" are black-and-white films with clear visuals and vivid character designs. They played an active and agitational role in rousing the Chinese people to resist Japanese aggression. At the same time, they demonstrate that early Chinese animation, from its very beginnings, was not merely a form of amusement or entertainment for idle enjoyment. Instead, it closely aligned with the contemporary struggles of the era, charting a course distinct from that of European and American animated films.
