The five elements produce restraint and turn into appropriate taboos
When metal is strong and fire is obtained, it becomes a vessel.
Metal can generate water, and if there is too much water, metal will sink; if metal is strong enough to get water, its edge will be blunted.
Metal can overcome wood, but if there is too much wood, gold will be lacking; if wood is weak and meets metal, it will be cut down.
Gold depends on the soil, and if there is too much soil, it will be buried with gold; if there is too much soil, it will produce gold, and if there is too much gold, the soil will change.
