A method for this practice connects the twelve Earthly Branches, representing time, to the bāzì (“BA-dzuh”). A method for this practice was largely replaced by the three-coin method. The King Wen sequence for this practice arranges broken and unbroken (10[1])lines. A text concerning this practice was accompanied by a set of commentaries called the Ten Wings. Yarrow stalks were used for this practice to generate hexagrams. The I Ching primarily concerns this practice, for which the Shang Dynasty used ox or turtle bones.
