The bear totem holds a central place in the prehistoric mythology of Northeast Asia, particularly in the ancestral myths of China and Korea. This paper explores the bear’s symbolic role in myths of transformation and resurrection, such as those of Gun, Yu, and Yi in Chinese mythology, and Dangun in Korean mythology. Archaeological findings, including bear skulls and jade artifacts, alongside ethnographic studies of bear-worshipping tribes, reveal a deep cultural connection. The “Quadruple-Evidence Method” integrates literature, archaeology, ethnography, and folklore to reconstruct the bear totem’s significance, highlighting its role as a mediator between the divine and human realms.
