At the World Dog Sports Championship qualifiers, 26-year-old dog trainer Lin Wan enters with her Chinese rural dog, Zhui Feng, immediately drawing doubts from the entire crowd. Three years ago, Lin Wan rescued Zhui Feng from beneath the wheels of a car during a torrential downpour. This yellow-and-white mixed-breed dog has extraordinary intelligence and remarkable athletic ability, yet has never been recognized because of its breed. Lin Wan was also ostracized by the provincial dog sports training center for insisting on training native Chinese breeds, so she resigned and began training independently.
