Fire (Chinese: 火; ||pinyin]]: huǒ), is the prosper of the matter, or the matter's prosperity stage. Fire is the second phase of Wu Xing.
Fire is yang in character. Its motion is upward and its energy is expansive. It is associated with Summer, the South, the planet Mars, the color red (associated with extreme luck), hot weather, daylight, and the Vermilion Bird (Zhu Que) in the Four Symbols (which is associated with a red phoenix in Western culture).
In Chinese Taoist thought, Fire attributes are considered to be dynamism, strength and persistence; however, it is also connected to restlessness. The fire element provides warmth, enthusiasm and creativity, however an excess of it can bring aggression, impatience and impulsive behavior. In the same way, fire provides heat and warmth, however an excess can also burn.
In Chinese Medicine, fire is associated with negative emotions of hate and the positive emotion is joy. The organs associated with this element are the heart (yin), tongue, and a body's pulse.
Flying Star Feng Shui uses number 9 to represent Fire. The South corner releases energy of Fire as I Ching and Feng Shui states. It is generally referred as energy of destroying and rebuilding. It also directly relates to a lucky lovelife.
Cycles of Wu Xing
In the regenerative cycle of Wu Xing, wood engenders Fire as "fire is generated by rubbing together two pieces of wood" and it must be fueled by burning wood; Fire begets earth as "fire reduces everything to ashes, which become a part of the earth again".
In the conquest cycle, water overcomes Fire as "nothing will put out a fire as quickly as water"; Fire overcomes metal as it "can only be melted and forged" by flame or heat.
