《周书·列传·卷四十五》
到浅黄色绸做书衣的书卷起火焰盛行，洁素的文章随从轻风流行，文辞追逐不同时代而变化，文义随时运而不同，大礼在玉帛之中保存，最好的声乐在钟鼓乐器之外表现。
及青缃起焰，素篆从风，文逐世疏，义随运舛，大礼存于玉帛之间，至乐形于钟鼓之外。
Paper scrolls in light yellow silk covers rise in flames, flourishing; elegant and concise essays follow the gentle breeze, flourishing. Literary style pursues change in different eras, and literary meaning differs with the course of events. Great ritual is preserved in jade and silk, and the best music and song are expressed beyond bells and drums.
