The Wood Element San He Combination is known as Hai Mao Wei (亥卯未). It involves the Earthly Branches of Hai (亥), Mao (卯), and Wei (未). When these branches are present simultaneously, it is said to create an overly strong Wood element. This combination plays a significant role in understanding the balance and influence of elements in Chinese metaphysics, particularly in relation to personal destiny and character traits.
