Yangmu's twin brother, Zhuozhuo, died at birth, so her father, Wujin, raised her as a boy. Determined to fulfill her father's dream, she resolved to compete in horse racing and devoted herself to the traditional sport. Riding across the snow-covered Tibetan Plateau, she honed her courage and skill through the trials of speed and endurance. In the end, she fulfilled her promise by becoming the first woman in the history of the Tibet Autonomous Region to officially compete in and finish a traditional horse race.
