Yilin Verse
野鳶山鵲，奕棊六博；三梟四散，主人勝客。
Wild kites and mountain magpies play chess and liubo; three owls scatter in four directions -- the host defeats the guest.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder breaks from the earth as wild kites and mountain magpies descend upon a game board. The verse depicts a contest of strategy — chess or liubo, the ancient dice-and-board game. Three pieces are 'owled' (captured) and four scattered; the host defeats the guest. The bird imagery suggests cunning, opportunistic players, while the decisive outcome favors the one who holds the home position. From Enthusiasm to Splitting Apart, the transformation is fitting: the mountain crumbles from the earth as the loser's position disintegrates. In Splitting Apart, yin lines erode yang from below until only the top remains. The defeated guest's forces are systematically dismantled, stripped away piece by piece, exactly as the hexagram describes.
