1, judging from the case, is to give up on yourself and obey. A strong yen makes it stronger, and a weak yen makes it worse. When hitting the yen is too strong and the fate of the main branch of the yen is not good, or when all the main branches in the bureau help the yen and there is no main branch to help the yen, such a fate is called "taking the spirit from Wang Ge" to help the yen. On the other hand, if the yen is too weak, the chart will not be supported by the yen, or it will not be supported by the yen. This fate is called "starting from a weak case", and using God is supported by yen. Whether it is strong or weak, it is collectively called "accessory case".
