Commander selection: this law is based on the commander's heavenly work in the monthly order. But the commander's heavenly stem is not necessarily the main qi in the monthly order, and sometimes it is not even one of the five elements in the monthly order. This will make it more difficult to judge the pattern and even make mistakes.
Uncovering the dry selection case in monthly order: This method is based on the monthly collection and uncovering the heavenly stems. But sometimes the Tibetan stems in the moon may not appear, or the heavenly stems that appear are not the strongest five elements. At this time, if you still insist on revealing the situation on a monthly basis, it may lead to inaccurate judgment of the pattern.
Eight-character month rush problem: Eight-character month rush refers to heavenly stems and earthly branches corresponding to a person's birth month and heavenly stems and earthly branches corresponding to his birth year. This kind of conflict will have a certain impact on a person's character and destiny, however, the specific way and degree of this impact is not easy to determine. This increases the difficulty and complexity of the moon grid method.
Generally speaking, the problem of the method of selecting monthly orders mainly focuses on how to accurately judge the pattern and how to deal with some special situations, such as the fact that the gas in the monthly order is residual and the gas is dry, the generals are not the main gas, the hidden work is not obvious, and the eight-character monthly order is rushed. In order to better apply the monthly subscription method, it is necessary to conduct in-depth research and discussion on these issues.
