《文心雕龙·原道》
将文章的理念推广到世间万物，无论是动物或植物都有文章可循。龙和凤以美丽的鳞羽，表现出吉祥的征兆；虎和豹以身上的花纹，来呈现英姿。云霞的彩色，比画师的点染还美妙；草木的花朵，也并不依靠匠人来加工点缀。
傍及万品，动植皆文∶龙凤以藻绘呈瑞，虎豹以炳蔚凝姿；云霞雕色，有逾画工之妙；草木贲华，无待锦匠之奇。
Expand the concept of literature to all things of the world. Whether it is animals or plants, they all have some form of literature. The dragon and the phoenix use their beautiful scales and feathers to represent auspicious signs; the tiger and the leopard use their body patterns to show off their heroic posture. The colors of the clouds and mists are more beautiful than the dyeing of the painter; the flowers of the trees and grasses do not rely on the artist to add embellishments.
