Wood (Chinese: 木 ||pinyin]]: mù), sometimes translated as Tree, is the growing of the matter, or the matter's growing stage. Wood is the first phase of Wu Xing. Wood is yang in character. It stands for springtime, the east, the planet Jupiter, the color blue, green, wind, and the Azure Dragon (Qing Long) in Four Symbols. The Wu Xing are chiefly an ancient mnemonic device for systems with 5 stages; hence the preferred translation of "tree" over "wood".
