Jingwei

Jingwei () is a bird in Chinese mythology, who was transformed from Yandi's daughter Nüwa. She is also a goddess in Chinese mythology. After she drowned when playing in the Eastern Sea, she metamorphosed into a bird called Jingwei. Jingwei is determined to fill up the sea, so she continuously carries a pebble or twig in her mouth and drops it into the Eastern Sea. Provided by Wikipedia
