The geomantic aspect of the ancient village site selection is said to occupy the bionic image of "two dragons playing with pearls". The village proverb says that "Erlong plays Zhuhougou Village in the Longmen River, four miles away". The visible basis of geomantic omen is mountains and rivers, that is, mountains and water. Feng shui masters believe that "getting water is the best, and taking shelter from the wind is the second". If you want water, you can't leave the river. If you want to take shelter from the wind, you have to rely on the mountain. The mountain pays attention to "the original terrain of the mountain, the original bone of the mountain". Hougou Village is backed by the branch of Taihang Mountain, with the main peak at an altitude of1342m. The mountains are undulating, like water waves, and Malik is rushing and drifting away, as if fighting for a drink on the bank of a small river. Longmen River originates from the hinterland of Luoyao Mountain, and flows down with the trend of Yang Shan to join the small river. Longmen water has formed a land of four spirits in Hougou ancient village. Luoshan in the north is blue, Junping in the south is dancing like a rosefinch, Qinglong in the east is winding, and the white tiger in the west is gentle. The ancestors of Hougou ancient village called the loess beam in the east of the village black dragon, the beam in the west of the village yellow dragon, and the junping opposite the village formed a spider, forming a bionic artistic conception of "playing with pearls in a double dragon" as a whole, forming a festive, auspicious and lively idea of village site selection. Traditionally, Erlong Mountain and Spider Mountain are forbidden and sacred mountains in the hearts of villagers, and farming, grazing and fire are forbidden.
