一条线绕成一个十字:中间是一块方地,四条边各向外让出一个方口,绕回来正好闭合。骨片上有的把它刻成一圈封闭的轮廓,有的干脆四个角各刻两笔,中间空着不连。一條線繞成一個十字:中間是一塊方地,四條邊各向外讓出一個方口,繞回來正好閉合。骨片上有的把它刻成一圈封閉的輪廓,有的乾脆四個角各刻兩筆,中間空着不連。One line runs round into a cross: a square in the middle, with each of the four sides stepping outward into a square opening before the line closes on itself. Some pieces cut it as a closed ring; others cut just two strokes at each corner and leave the middle open.
