The five elements coexist: water is like fire, fire is like gold, Jin Kemu, wood is like soil, and soil is like water.
Jin Kemu, because cutting tools made of metal can cut down trees. There is no grass on the mined land.
Fill with water, because the soil can be waterproof. Soldiers will block the water and have ways to cover it.
Water suppresses fire, because fire goes out when it meets water.
Hawkin, because fire can melt metal.
Extended data:
Coexistence of five elements: wood makes a fire. Fire produces soil, soil produces gold, gold produces water, aquatic wood.
Wood makes a fire because it is warm, and the fire is hidden inside, so wood makes a fire.
Fire can burn wood because heat produces soil. Wood turns to ashes after burning, and ashes are soil, so fire produces soil.
Primary gold, because gold needs to be hidden in the stone and attached to the mountain, it is moist and born. When the soil is gathered into a mountain, the mountain will produce stones, so primary gold.
Gold begets water, because the qi of Shaoyin (golden gas) is moist and flowing, gold depends on water, and forged gold can also be turned into water, so gold begets water.
Aquatic wood, because the water is warm and humid and trees grow, aquatic wood.
Refer to Baidu Encyclopedia-the five elements are mutually reinforcing.
