Fengshui Mountain is sitting on our mountain, facing Guishan. Is it due south?

The questioner wrote one or two more "mountains" on the topic, which made the question vague and complicated, and the respondent was in a dilemma. The best answer is right, and I think it needs to be added.

According to the content analysis of the seat orientation expressed in front of the question topic, sitting in Dingshan (the word mountain is dispensable, and the seat is the same as the mountain) is neither ugly nor ugly. According to the idiom "sitting in a certain direction", it should be: sitting in Ding is not ugly, but ugly (in fact, ugly in Guangxi) and ugly in Northeast China (66)

But according to the last question, whether this direction belongs to due south, it is true that the direction of northeast 15 degrees is a little different from that of south. Perhaps the original intention is to ask whether the direction of "sitting with ugly back" (southwest 15 degrees or above, that is, south 195 degrees or above) belongs to due south, but the questioner has probably read some Feng Shui books. If so, it is not due south, because due south is noon, that is, within 3 degrees before and after 180 degrees (noon is within 172.5- 187.5 degrees). The subdivision of geomantic omen is 24 directions. Although the directions of Ding and Wei are close to noon, they are definitely not inward, let alone due south. Concepts should not be confused.
