carriage, driven by Xihe, the 'mother' of the suns. As soon as one sun crow returned, another one would set forth in its journey crossing the sky. According to Shanhaijing, the sun crows loved eating two grasses of immortality, one called the Diri (), or "ground sun", and the other the Chunsheng (), or "spring grow". The sun crows would often descend from heaven on to the earth and feast on these grasses, but Xihe did not like this; thus, she covered their eyes to prevent them from doing so. Folklore also held that, at around 2170 BC, all ten sun crows came out on the same day, causing the world to burn; Houyi, the celestial archer, saved the day by shooting down all but one of the sun crows. (See Mid-Autumn Festival for variants of this legend.) The sanzuwu is also depicted with the Queen Mother of the West () who are believed to be her messengers. Other tripedal creatures in Chinese mythology In Chinese mythology, there are other three-legged creatures besides the crow, for instance, the yu "a three-legged tortoise that causes malaria". The three-legged crow symbolizing the sun has a yin yang counterpart in the chánchú "three-legged toad" symbolizing the moon (along with the moon rabbit). According to an ancient tradition, this toad is the transformed Chang'e lunar deity who stole the elixir of life from her husband Houyi the archer, and fled to the moon where she was turned into a toad. The Fènghuáng is commonly depicted as being two-legged but there are some instances in art in which it has a three-legged appearance. Xi Wangmu (Queen Mother of the West) is also said to have three green birds () that gathered food for her and in Han-period religious art they were depicted as having three legs. In the Yongtai Tomb dating to the Tang dynasty Era, when the Cult of Xi Wangu flourished, the birds are also shown as being three-legged. Japan In Japanese mythology, this flying creature is a raven or a jungle crow called Yatagarasu and the appearance of the great bird is construed as evidence of the will of Heaven or divine intervention in human affairs. Although Yatagarasu is mentioned in a number of places in Shintō, the depictions are primarily seen on Edo wood art, dating back to the early 1800s wood-art era. Although not as celebrated today, the crow is
