"Shuo Wen Jie Zi" contains: "The dragon, the scale worm's length, can be quiet and bright, can be fine and huge, can be short and long, the vernal equinox reaches the sky, and the autumn equinox is deep."
Erya, the founder of the dictionary, mentioned the image of the phoenix, but said nothing about the dragon. In the addendum to Er Ya Yi written by Luo Yuan in Song Dynasty, there is a "dragon interpretation": "horns are like deer, heads are like camels, eyes are like rabbits, necks are like snakes, bellies are like flies, scales are like fish, claws are like eagles, palms are like tigers, ears are like cows". Guo, who is also an appraiser of calligraphy and painting in the Song Dynasty, also expressed similar views in his paintings.
In the Ming Dynasty, the image of the dragon became more specific and full. "Wings of Compendium of Materia Medica" said: "The dragon is the first of the scale worms. A king has nine shapes: his head is like a camel, his horns are like deer, his eyes are like rabbits, his ears are like cows, his neck is like a snake, his belly is like a stork, his scales are like carp, his claws are like eagles, and his hands are like tigers. It has 8 1 scales on its back, and the number is nine and nine yang. It sounds like a coin. There is a beard near the mouth, pearls under the chin and scales under the throat. There is Boshan on the head, also known as ruler wood, and the dragon can't ascend to heaven without ruler wood. Breathing into the clouds can turn into fire and water. "
