What is the meaning of "filling food" in four pillars and eight characters?

Filling. Generally speaking, there are two kinds of statements.

The first one is that when the four pillars are empty, generally speaking, when the Universiade meets the same word or meets the rush, it will be filled in. For such people, evil spirits are generally full of evil spirits, while auspicious ones are full of good luck.

The second is the arch bureau, which arches a word like a dry day, such as Jiayin and Chen Jia. Or the three-in-one bureau supports the arch word Wang Di, such as Chen Shen arch. For most arches, no matter whether the original word is good or bad, the deficiency is good and the filling is evil.

Simply put, it is to look at fate.
