What's the word for lack of fire in four pillars and eight characters?

The eight characters mainly look at the circulation and pattern of the momentum, as well as avoiding the spirit with the gods, and then the luck of the New Year is basically started from these aspects. As for the lack of five elements, that is secondary. In fact, it is too common for eight characters to lack one or two elements. For example, a person is born with poor eyesight, even if he wears glasses, his eyesight is still poor and cannot be fundamentally changed. The same is true of the eight characters. We should start with the Eight heavenly stems and earthly branches in primitive life, instead of running outside to find our way.
