From a macroscopic perspective of site selection for building houses, Feng Shui theory places great emphasis on the orientation, terrain, and the layout of surrounding mountains and waters of a building. The site selection pattern of facing water in the front and having a mountain at the back, with a south-facing orientation, is often regarded as an ideal choice. The mountain behind is like a solid support, providing a sense of security for the occupants; the flowing water in front is akin to vibrant wealth and vitality, bringing a continuous stream of energy; and the south-facing orientation is conducive to receiving sunlight, filling the living space with warmth and brightness, as if resonating with the rhythm of nature, creating a comfortable, auspicious living environment for the occupants. For example, the renowned Forbidden City in Beijing was ingeniously constructed in accordance with Feng Shui principles. The magnificent palace complex is located on the central axis, with the Golden Water River meandering in front and Jingshan Hill standing majestically at the back, and a symmetrical and balanced layout on both sides, demonstrating the royal majesty and dignity. After hundreds of years of vicissitudes, it still exudes a unique charm and aura, inspiring awe and admiration.
