In the bazi science classical literature <Yuan Hai Zi Ping> written in the ancient china song dynasty, there is a chapter talking about the 5 elements inter-relationship with each other in terms of the chemical effects into create , destroy, restraint and defuse, with examples for illustration.
- Strong tough metal needs fire so as to become tools for operating;
- Strong fire needs water so as to control and balance the heat for refinery;
- Massive water needs earth so as to form up pool and swamp for useful storage ;
- Strong hard earth needs wood so as to loosen soft into planation land;
- Strong huge wood needs metal so as to make into concrete pillars for building.

渊海子平 - 《论五行生剋制化》
金旺得火,方成器皿;火旺得水,方成相济;水旺得土,方成池沼;土旺得木,方能疏通;木旺得金,方成栋樑.
