There is a passage in The Journey to the West, in which the green ox rode by the old gentleman in Taishang descended to earth and became a fine beast, making a circle and trapping many gods' weapons. This green cow is just a pig. Wu Cheng'en wrote it well: "A corner is uneven, but two eyes are clear. The top is rough and the ears are black and fleshy. When the tongue grows, it stirs the nose, and the mouth is wide and yellow. The fur is as blue as indigo and the tendons are as strong as steel.
