Why are the eight characters on the Internet different?

XiShen is the core of the eight characters, and it is difficult to choose a god because there are no rules and unified formulas for choosing a god in the eight characters, so most people who are in favor of the eight characters can only choose a god at will through simple judgment, so choosing a god is like playing a lottery. But there are only five gods to choose from, that is, fire, water and earth in Jin Mu. There is support, adjustment, customs clearance, strong support and weak support. This is the most basic way to choose gods, and some choose gods in a pattern, which is even more chaotic. The choice of God's face is mostly centered on support, but some characters are not allowed to use support to choose God. This is the randomness of learning eight characters and choosing gods, which makes it different. thank you
