Yilin Verse
黃裳建元，福德在身。祿祐洋溢，封為齊君。賈市无門，富寶多飱。
Yellow robes inaugurate a new era; fortune and virtue upon his person. Blessings and favor overflow; enfeoffed as Lord of Qi. Trade flourishes without obstruction; wealth and fine provisions abound.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Twin mountains stand still, and a figure in yellow robes inaugurates a new era. Blessings and virtue rest upon him; fortune and favor overflow as he is enfeoffed as lord of Qi. The market needs no gates — wealth and food abound. 'Yellow lower garment' (黃裳) quotes the Kun hexagram's fifth line: the golden mean of receptive excellence. 'Establishing the primal year' (建元) signals the founding of a new reign. The figure may allude to the Taigong (Jiang Ziya), who was enfeoffed at Qi after the Zhou conquest. From Keeping Still to the Joyous, mountain yields to doubled lake — shared delight, open exchange. The mountain's contained power flows outward as communal prosperity, markets so abundant they need no walls.
