Relatively speaking, the house and life should be dominated by the five elements of the house, because the good and bad effects produced by the eight houses and nine planets are far greater than the interaction between them. For example, the cosmic environment is an acidic solution and the living environment is an alkaline solution, so man is a molecule of alkali or acid, and his five-element field is relatively small, and his interaction with the environment is also small. So it is mainly based on the big environment. For another example, a big ship is sailing at sea, people are on board and the ship is at sea. The sailing process should be based on the general environment, not the captain's will. Even if he has the initiative, it is based on big conditions. As long as God can arrange his transportation flexibly.
