Some books say that the southeast is Kun, while others say that the southwest is Kun. Which one is right?

It is based on the direction of Kun, so it is generally based on the southwest. You said that there is a book called the position of Southeast Kun, and it is not groundless. The southeast is the location of Kun, and sages and great wisdom are afraid that the southeast is too low. To transfer Kun to the specific right and wrong, we have to leave this problem to each yogi to experience.
