Beitou (北頭)means "witch" in the language of the Pingpu Tribe, and Yang means grassland that can sustain livestock. This place has a legend, in which a Pingpu man called Feifan can run faster than a horse, and even won a race against a horse in the presence of the Qianlong Emperor. The Emperor's heart was so filled with joy that Feifan and his son were honored to see the emperor three times. Nowadays, lots of informational exhibitions on the Siraya Pingpu are held in the park, and there are traditional huts, old photographs and Feifan sculptures.
