Long Mai refers to the rolling mountains, and the ancient geomantic omen pioneered "five geographical techniques", namely "finding dragons, inspecting sand, watching water, acupoints and standing upright". Dragon is the geographical context, soil is the meat of dragon, stone is the bone of dragon, and vegetation is the hair of dragon. Looking for dragons, we must first find the mountains of ancestors and parents, judge the pulse, don't be angry, and divide yin and yang. You must know the cause and effect before you can judge the cause and effect.
It is recognized by geomantic circles that Kunlun Mountain is "the ancestor of Wanshan Mountain and the source of Long Mai" and the ancestor of dragons. Long Mai started from Kunlun and spread all over the world. The layout, structure and classification of Long Mai are similar to a big tree, including root dragon, stem dragon, branch dragon and Ye Long. Generally speaking, the place where Long Mai's aura gathers (blossoms and bears fruit) is considered as a treasure trove of geomantic omen (Longdong).
