The work aims to address the lack of localization in facial exaggeration of contemporary animated characters in China and to attempt to make a cognitive and methodological breakthrough in the exaggeration tendency. By analyzing the differences between the exaggeration of animated character design in the East and the West, the shortcomings and the key points for breakthrough of contemporary Chinese animation in exaggeration are pointed out. With the help of the animation face generation platform, a large number of animation faces are quickly generated from real-life photos. And based on comparative analysis and manual intervention, the key points of generative exaggeration and its application in animated character design are summarized. According to the heads and faces features of East Asian race and the traditional Chinese facial science theory, other factors influencing facial exaggeration in local animated character design are explored. The conclusion is that "increasing the distance between the eyebrows and eyes universally" and "preserving or exaggerating asymmetries universally" are generative exaggerated points in animation generation that are suitable for local animation character design. In addition, there should also be a variety of exaggerations in the areas of "geometric exaggeration of the face", "characterized exaggeration of the five sense organs", "addition of details common to Chinese faces", "exaggeration of age" and "exaggeration of the art style". And while AI-generation methods can suggest ideas that can be drawn upon for animated character design, the application of AI-generation in art and design research cannot be done without the guidance of traditional cultural theories and artists.
