What does it mean to ask for help from gossip "empty death"? Is there a specific way to judge?

Empty death, also known as Xunkong, is a "vacancy" or "discontinuity" in the time flow of trunk branches. In fact, ten days of trunk branches are matched with twelve earthly branches, and the remaining two earthly branches cannot be dominated. These two earthly branches are "empty death". The gossip associated with the dead earth branch is also the divination of Xunkong. For example, Jiazi is in the dry palace, that is, the dry divination is empty. These are the basic knowledge of "Shu Shu". Look for more introductory books yourself.
