There are 3 interactions (cycles): productive, exhausting and destroying.
In the productive cycle: water creates wood, wood produce fire, fire produce earth, earth creates metal and metal creates water and so on…
In the exhausting cycle:
In this cycle elements exhaust each other. Wood exhausts water (when we place flowers to water, it will consume it), water exhaust metal (it causes corrosion of metal), metal exhaust earth (gold and other metals come from earth,), earth exhaust fire (when you pour earth on fire it will die), fire exhaust wood (causes fires of forests) and so on…
You can find the chart below.
In the destructive cycle:
Water destroys fire (when there is fire you use water), wood destroys earth (trees deplete the energy of earth), fire destroys metal (metal is melting when you use fire), earth destroys water (soak), metal destroys wood (cut it down).
Below there is a chart.
You can actually use it yourself by applying the theory in your surroundings.
