Please tell me how to determine the orientation of Tiande, thank you!

First of all, you should know the formula of Tiande 12 months. In a certain month of each year, Tiande's position will change and is not fixed. Second, the dry branches fled with the five tigers that month, and third, they flew with the nine palaces, entered the middle palace with the dry branches that month, and flew along the nine palaces, and it was over. For example, July 2065438+2008 is the month of Geng Shen, and Geng Shen entered the palace, which means that seven decyl and eight gen meet. This dun is the sea of decyl, and Jiugong flies three steps to gen, which is the birth orientation of this month.
