During the reign of the Yongle Emperor (early 15th century), his relative from Kaifeng sent him a captured "zouyu" (騶虞), and another "zouyu" was sighted in Shandong. "Zouyu" is a legendary "righteous" animal, which, similarly to a "qilin", only appears during the rule of a benevolent and sincere monarch. It is said to be fierce as a tiger, but gentle and strictly vegetarian, and described in some books as a white tiger with black spots. Puzzled about the real zoological identity of the creature captured during the Yongle era, J.J.L. Duyvendak exclaims, "Can it possibly have been a Pandah?"
