Baí Zé (simplified Chinese: 白泽; traditional Chinese: 白澤; Wade–Giles: Pai Tse), or hakutaku (白澤) in Japanese, is a fantastic beast from Chinese legend. Its name literally means "white marsh". The Baí Zé was encountered by the Yellow Emperor or Huáng Dì while he was on patrol in the east. Thereafter the creature dictated to Huáng Dì a guide to the forms and habits of all 11,520 types of supernatural creatures in the world, and how to overcome their hauntings and attacks. The emperor had this information written down in a book called the Bái Zé Tú (白泽图/白澤圖). This book no longer exists, but many fragments of it survive in other texts.
