股肱（上公戶反髀也下古弘反臂也案股肱即手足也尚書云股肱惟人孔傳云手足具乃成人又曰元首明哉股肱良哉是也）。

股肱 (The first character has the fanqie 公戶 [gǔ], meaning thigh. The second character has the fanqie 古弘 [gōng], meaning upper arm. On examination, 股肱 refers to the limbs [arms and legs]. The Shangshu states: 'Legs and arms make the man.' Kong's commentary states: 'Only when hands and feet are complete is one a person.' It also states: 'When the head is enlightened, the limbs are good.' This is it.).
