What does seeking emptiness in Fude Palace stand for?

It has something to do with the arrangement in the sixties. There are ten heavenly stems, ten ten days, and ten heavenly stems with twelve earthly branches, but there are twelve earthly branches, so there are two earthly branches without heavenly stems, and these two earthly branches are the locations for patrolling the sky. Xunkong was found according to the date of birth and the location of the corresponding branch. But remember, it is right to use sunny or cloudy branches, and it is empty on sunny or cloudy days. The positive force is strong and obvious, while the near-air force is weak and hidden, which will only be revealed when necessary.
