《淮南子·时则训》
在这个月里，主管工匠的官员考核工匠们的工作成效，将所制作的祭器陈列出来，并察看其规格质量，以坚固精致的为上品。
是月也，工师效功，陈祭器，案度程，坚致力上。
In this month, the chief artisan examined the work performance of artisans, displayed the ritual vessels they had made, and inspected their specifications and quality. Those that were strong and exquisite were considered the best.
