Question of six benevolence: Which expert can tell me something about the role of the star sum and division in six benevolence?

Twenty-eight lodges were used by the ancients to mark the relative position between the earth and these twenty-eight lodges. The stars in the six roots are used to assist elephants, for example, the elephants in the six roots are not wells, because there are no wells in them. The name of the survey can be Jing. For example, in the afternoon, the surname may be Liu and Zhang, because there are Liu and Zhang staying for two nights in the afternoon. The second is to determine the dividing line, that is, to measure the corresponding geographical position. For example, in ancient times, it was decided where the official was. The corresponding position is recorded in ancient books, such as the place where the son is Youyan. However, because the location of the ancient Twenty-eight Hostels is different from today, no one has repositioned the Twenty-eight Hostels according to astronomy in modern times, and whether it can be used is still inconclusive. It is said that some people now think that it should be the Shanxi generation, not the ancient Hebei and Beijing areas. My opinion is for brother Huang's reference.
