How to choose urban architecture residential feng shui?

There are four main elements in the choice of geomantic environment in residential geomantic omen, namely dragon, sand, cave and water, among which "dragon" is the most important, without which sand and cave are impossible, followed by "water". However, most of the cities we live in today do not have "real mountains (dragons) and real water". What about "dragons" and "water" in urban housing? How to choose Feng Shui in turn? The ancients once divided houses into three categories: one is the house of luxury; Second, the house of the wilderness; House of the valley. Urban housing belongs to the first kind of Jing Yi house. There is a poem in the entry "Looking at the Dragon" in the first volume of "Yang Zhai Integration": "On the street of 10,000-tile scale, the roof of Gao Lian is the origin and development. Although the dragon will reach the sky, it must be an original. " That is to say, the roofs of ten thousand houses that are densely connected are regarded as winding and undulating Long Mai. What about the water in the "dripping world"? "Lord Yang Zhai" said: There are ten thousand households in the city. Although there are causes and effects, it is a business matter, which can test the rise and fall of the overall situation, not the luck of one family. These houses don't talk about dragons by ridges, but only by streets ... The way to collect gas is to use streets as water covers. "Yang Zhai Hui Xin Ji" says more clearly: "The first floor of the street is water, and the wall room is covered with sand. The street in front of the door is a hall, and the opposite room is a mountain." So there is: "It is not advisable to see the corner in front of the building, and it is not advisable to have a straight ridge behind the house." In a word, it is equivalent to the choice of the geomantic environment of the village house: the current in front of the house should not be sharp and straight, and the Long Mai behind the house should be winding but not stiff. Feng Shui attaches great importance to the source of "Qi". Tens of thousands of families have the most energetic and lively people living in their houses, and the "airway" can definitely be compared with the ups and downs of mountains. Geomantic omen pays attention to "hiding wind and gathering gas", and urban residential buildings can really play a role similar to that of mountains, especially those tall buildings; Feng Shui attaches importance to "guiding and binding qi". As the saying goes, when gas comes, it is guided by water, and when gas stops, it is bound by water. Busy streets must have the function of "guiding air", while uninhabited wide roads must have the function of "bundling air", so urban streets naturally play a role similar to "water"? Feng Shui believes that "the inside and outside are tangible", that is to say, what kind of shape, what kind of connotation, what kind of role will it play. Because the buildings in the city have the same shape and streets as mountains. Feng shui pays attention to "happiness and affection", and urban houses are afraid of straight streets; Feng shui pays attention to "mountains are surrounded by water", urban houses are afraid of the wind, and streets are arched; Feng Shui pays attention to "don't live in the valley", while urban houses are afraid of "cutting the sky" (the narrow gap between two tall buildings); Feng shui pays attention to "winding ups and downs", while urban houses are afraid of being stiff (such as tall chimneys), and so on.
