The so-called melting gas into the cave refers to the phenomenon that "gas" produced or attracted by the gas-gathering effect of the Feng Shui Bureau gathers into the cave in a Feng Shui Bureau.
The phenomenon of "entering the first place" is the most common in Long Mai geomantic omen. Observing the trend of "entering the first place" is one of the essential steps in the process of surveying the good and bad luck of dragons.
Long Mai's "No.1" status is directly related to the good or bad of the whole Long Mai. If the entrance of Long Mai is full and full of vitality, it can be judged in principle that this Long Mai is a "real dragon" that can get rich and expensive. The more correct the entrance, the better the gas gathering effect and the long-term wealth. If the entrance is not right, there will be "air leakage" or "stopping evil" failure, and the wealth will be weak, and even directly become a fierce game.
Long Mai's entry into the first place is generally divided into five situations: flying dragon entering the first place, dragon returning to the first place, straight dragon entering the first place, horizontal dragon entering the first place, and hidden dragon entering the fifth place.
"Flying Dragon at the Head" refers to the situation that Long Mai has come to an end with great momentum and surrounded by mountains. This "first place" situation is the most auspicious and generally expensive.
"Returning the dragon to the first place" means returning the dragon to the end of the mountain, fighting against the sand, and being upright. This "first place" situation is most beneficial to future generations.
"Go straight" means that although Long Mai was stripped and replaced layer by layer, it was still like a rainbow and crashed into the cave. This "first place" situation is rich, but generally it can't last.
"Crossing the dragon into the head" means that Long Mai's knot is on his side, which mainly depends on the shape of his ancestors (mountains) and the yin and yang orientation of his head.
"Hidden dragon into the head" generally means that on the plain, Long Mai lurks all the way to the head, surrounded by water. The main reason for this situation depends on the water, direction, yin and yang, orientation and other specific conditions at the junction.
Some theories think that "entering the first place" only refers to the integration of Feng Shui in Long Mai, but in fact, the scope of "entering the first place" is not limited to Long Mai.
In any geomantic omen bureau, as long as "Qi" flows into air pockets, poles, etc. , can be called "into the head". For example, in a house, the "qi" generated or attracted by the Feng Shui Bureau of the house itself gathers on the "financial position", and this process can also be called "entering the first place".
