东西我们往往把一切物体统称为“东西”。但为什么称“东西”而不称“南北”呢?原来我国古代把木、火、金、水、土称为“五行”,分别代表东、西、南、北、中。把甲、乙、丙、丁、戊、己、庚、辛、壬、癸称为“天干”,又把“五行”、“天干”对应起来,组成“五方”,即东方甲乙木 We often refer to everything as “something”. However, why is it called “the east and the west” instead of the “north and south”?

We call A, B, C, D, E, J, G, X, 壬, and 癸 “ the “Tian Gan” and the “Five Elements” and “Heavenly Stems” to form the “Five Parties,” namely, Oriental A, B, and B.
