Carpenter's square (矩方, the first character is pronounced j[ǔ]-l[iǎng] fan; the Shiben says: "Chui made the compass and the square." The Guangya says: "矩 means square." Zheng's commentary on the Kaogong ji says: "That by which a standard is set. Furthermore, a man's height is eight chi, and the major joints are three: head, abdomen, and shins; dividing by three gives the standard measure of two chi, six cun, and two-thirds of a cun."
