甘龙 / Gan Long

甘龙 / Gan Long appears in 《资治通鉴·周纪》13丨 公孙鞅苛刻变法惹杀身（1） as the Qin-side opponent of 公孙鞅 / 商鞅 before the first reform order. The episode presents him as a defender of inherited custom and existing law: old arrangements may not be perfect, but forcing abrupt institutional change can unsettle people and social routines.

Gan Long matters because his objection is stronger than simple inertia. In the source’s reading, he recognizes that society has habits, expectations, and fragile legitimacy. His dispute with Shang Yang therefore becomes the episode’s central contrast between custom-sensitive governance and reform without popular deliberation.
