Look at the "dragon" first when you look at Feng Shui. The dragon is Long Mai, and the change of the dragon in Feng Shui represents the trend, ups and downs, turning and changes of the mountain. The main mountain is the "border", and the ridge winding down from the top of the mountain is called "Long Mai", also called "going to the border", from which the idiom "border" comes. Mountains have different directions, so dragons have different postures. Geomantic omen divides dragon potential into five types, namely: 1, and the north-south trend is called positive potential; 2. From west to east, it is called lateral potential; 3. Going against the current is called going against the trend; 4. Going downstream is called homeopathy; 5, the beginning and the end are called back. By the way, why is the dragon's lateral potential "from west to east" or "from east to west"? Master Feng Shui often divides Long Mai with four big rivers in China, which are called three dry dragons. The mountain range south of the Yangtze River is Nanlong, the mountain range between the Yangtze River and the Yellow River is Zhonglong, and the mountain range between the Yellow River and the Yalu River is Bellon. The starting point of Sanganlong is Kunlun Mountain, which is located on the Qinghai-Tibet Plateau in western China, so we should say "from west to east" here.
The second is to look at the "direction", which is the direction. "Feng Shui" wrote: "The dragon is facing west, so it is advisable to sit north to south (sunny slope); The dragon is in the north and south, and the site is on the east slope. The general principle is to face the mountain and face the water to avoid evil spirits. " The Xishan Mountain in Kunming is a north-south mountain range, that is, "Longteng North-South".
