What is "Tai Chi fixing points" in traditional geomantic omen?

There are more than a dozen explanations for the acupoints of Taiji, but it is easy to understand. From a distance, where there are acupoints, in a small range, they are usually at most one or two acres wide, just like the place where the tendons on the fingers are located, which is where the real acupoints are located. The big one is one or two acres, and the small abbot is wide. Seen from a distance, it looks like a tendon in the finger.
