What's the difference between "long luck" and "changing luck" of geographical geomantic omen?

Perhaps we can give an example of transportation in Longyun Mountain. 18, the fortune changed into a white fortune of binary mysterious divination and geomagnetic fortune, and the combination of congenital kunliuyin was 18. As for the thirty years in Hedong and Hexi, it may be two hexagrams in Jiangdong and Jiangxi, or it may be sixty jiazi with half yin and yang. In fact, it is an experience of changes in people's fortunes. My humble opinion is to help people who have no talent.
