《梦溪笔谈·器用》
又如蒲璧和谷璧，《三礼图》都在璧的表面上画几棵草或庄稼的图案作为它们的装饰，而现在世人发掘古墓所得到的蒲璧，却是刻纹茂密像蒲席的编织花纹铺开时的样子，谷璧则不过是璧的表面密排的圆形突起有如米粒而已，可见《三礼图》也未可作为依据。
如蒲穀壁，《礼图》悉作草稼之象，今世人发古冢得蒲璧，乃刻文蓬蓬如蒲花敷时；彀壁如粟粒耳。则《礼图》亦未可为据。
For example, the Pu Bi and Gu Bi, both in the "Three Ritual Diagrams", have a few grass or crop patterns painted on the surface of the Bi as their decorations, but the Pu Bi unearthed from the ancient tombs by modern people has dense engraved lines like the woven pattern of a rush mat when it is spread out, while the Gu Bi is nothing more than a bunch of round protrusions densely arranged on the surface of the Bi like grains of rice, so it can be seen that the "Three Ritual Diagrams" cannot be used as a basis.
