About
The character "矩" originally designated a carpenter's square used for measuring right angles, with its structure incorporating the radical "矢", implying straightness or alignment, and the phonetic component "巨". While its early meaning was confined to this physical tool, the term gradually expanded to denote abstract standards, rules, and normative principles in various fields.
