"Variety" is sometimes interpreted as the array method in ancient tactics: "Wuhua" is a five-element array; "Eight gates" is "Eight gates array". During the Spring and Autumn Period and the Warring States Period, many military strategists knew how to use this five-element array. The five elements refer to gold, wood, water, fire and earth. The ancients believed that the elements that make up all kinds of substances are the five elements. In addition, the five elements represent five pigments: red, yellow, blue, white and black. When they are mixed together, they can become many colors and make people see things in a blur.
Eight-gate array is also called Eight Diagrams Array. This array was originally listed as an array according to the ranking of gossip.
However, 88 can be changed to 64 hexagrams, which often confuses the opposing army. According to legend, Sun Wu and Sun Bin in the Spring and Autumn Period first used the Eight-Gate Array. Later, Zhuge Liang in the Three Kingdoms period changed the Eight-Gate Array into the Eight-Array Map.
