What does the southern movement in the eight characters mean?

What's the meaning of "southern transport" in the eight characters? It means that you are in a difficult situation in the south this year. Other southwest, northwest, west, east, west, north and south are all lucky, and there must be wealth in the south. I think that's what the southern movement in the eight characters means, that is, you only have the southern movement and don't know the other direction. In the eight characters, I think this is what it means. You can.
