What does the so-called "the sun has no roots" mean in the eight characters, and what does it mean to have roots?

There is no root in the sun, which refers to the eight-character sun column heavenly stem, and there is no heavenly stem similar to the sun column heavenly stem in the underground branch. The earthly branch is inclusive. A branch of the earth can hide up to three heavenly stems. For example, the yin's earthly branches and the hidden heavenly stems are A, C, E ... Then the Lord of the sun, if it is one, then it has roots. But for these three days, the Lord would have no roots. A horoscope has four earthly branches, and each earthly branch has to go to its Tibetan trunk to see if there is a heavenly stem like a solar column. If you can't find it, it means that the sun column has no roots. If you can find the same heavenly stem as the Japanese Lord in the Tibetan trunk of the earthly branch. Then this Lord has roots.
