Jingwei Fills the Sea

Originally, it refers to the story of Yan Emperor's youngest daughter, Nuwa, who drowned in the East Sea and transformed into the Jingwei bird. In anger, she vowed to fill the East Sea with pebbles and twigs. The idiom originates from the "Classic of Mountains and Seas - North Mountain Classic." Later, 'Jingwei Fills the Sea' came to symbolize holding a grudge and vowing revenge, or to represent unwavering determination and fearlessness in the face of hardship.
