《新唐书·列传·卷一百二十七》
到了宋之问、沈亻全期，又加浓艳婉丽，回避声韵上的疵病，规定字数、句数，使写诗如编织锦绣一样，学习者十分推崇，称之为 沈、宋 ，还说 苏、李居前，沈、宋并肩 。
及之问、沈佺期，又加靡丽，回忌声病，约句准篇，如锦绣成文，学者宗之，号为 沈宋 。
When it came to Song Zhiwen and Shen Ruquanqi, they further added rich and beautiful ornamentation, avoided flaws in pronunciation and rhyme, and stipulated the number of characters and sentences, making poetry writing like weaving brocade. Students of poetry greatly admired them and referred to them as "Shen and Song," also saying "Su and Li are in the lead, Shen and Song are on par."
