Garden site selection is the first work of gardening, that is, "phase of the ground", the garden environment before the garden selection. Chinese traditional garden site selection theory is undoubtedly governed by the theory of feng shui and the influence of its essence. The famous royal garden in the Northern Song Dynasty "Burgundy" site selection is according to the theory of feng shui to carry out. Southern Song Dynasty Zhang Hao "Burgundy" recorded Song Huizong just ascended the throne, there is no son, so asked the geomancy expert in geomancy, said "the northeast corner of the capital, the ground Concord Geomancy, but the situation is a little lower, if less high, then the heir to the emperor carries on." Eight trigrams in the northeast for the "Burgundy", according to the "I Ching", "Burgundy" and the prosperity of the descendants of the clan related. From low to high, the only way is to build a mountain, a pile of mountains based on the Royal Garden began to build, proficient in painting the Song Huizong personal planning, the garden into the title "Burgundy", and the introduction of Kaifeng City in the Jinglong River into the garden, so that it has become a poetic landscape garden.　From the Ming Dynasty gardening theory book "garden metallurgy" book on the theory of the garden site (phase ground), you can see the influence of feng shui thinking, the book reads: "the garden base is not bound to the direction of the terrain has its own high and low; Shibuimen into an interesting, get the scene with the shape, or alongside the mountains and forests, want to pass through the river and swamps. Explore the wonders of the near Guo, far from the thoroughfares; choose to win the village, through the differences in the deep trees. Villages overlook the wilderness, and cities are convenient for families. The new building is easy to open the foundation, and can only carry poplar and bamboo; the old garden is wonderful in the renovation, and the natural ancient trees and flowers. It is as square as a garden, as flat as a curve; as long and curved as a wall, as flat and wide as a cloud. The high side of the pavilion on the platform, low concave can open the pool and marsh; Buzhu expensive from the water, the foundation first on the source, dredging the source of the source, the origin of the water. ...... Bridge through the water, the pavilion can be charted; gathering stone base wall, living in the mountains can be compared. ...... The phase of the ground is appropriate, the garden is appropriate." From these words can be seen, the garden site is suitable for the location, according to the terrain of high and low curvature arrangement of the garden scenery; according to the mountains with water, to the basic structure of the landscape, the mountain because of the water live, the water with the mountain turn; comply with the feng shui theory of anorexia mansion "Buzhu" principle, choose a "heavenly, geographical, human and It follows the principle of "divination and construction" of Feng Shui theory, and chooses an ideal environment of "timing, location, harmony" in order to seek a psychological equilibrium.　Garden Metallurgy" in the "phase of the land" process of gardening land is divided into mountains and forests, urban land, village land, countryside, adjacent to the house land, lake land six types, especially mountains and forests, villages, countryside by the deepest influence of feng shui ideas, the most reflective of feng shui theory of the environment and landscape requirements. For example, mountain and forest land: "The garden is only the best in the mountains and forests. There are high and concave, there are curved and deep, there are steep and hanging, there are flat and flat, since the natural interest, do not bother the work of human affairs. Into the Austrian dredging source, on the low chiseling water, searching for soil to open its cave foot, cultivating the mountain to connect the room corridor. ...... Threshold teasing a few flower letters, the door bends a belt of streams, bamboo through the secluded, pine squatters secluded, ...... thousands of mountain ranges ringed with verdure, ten thousand ravines flow green." Village land: "Ancient people who are happy in the fields and gardens, living in the fields and acres; today, those who are delayed in the gullies and ravines, choose the victory of the village, the group of hedges, everywhere mulberry outlet; chiseling water for the city of dreams, picking the embankment planting willows; the gate building to know the crops, porch and even the rue. About ten acres of the foundation, to open the pool of three, zigzagging with love, sparse source can be; the remaining seven points of the land, for the base of four, no matter how low, carrying bamboo is appropriate." Countryside: "Countryside choice of land, to the Pinggang Quyu, stacked Long Qiaolin, water dredging through the source, the bridge across the water, go to the city is not a few miles, and to and from the city can be arbitrary, if for the fast also. Thanks to the ruggedness of the terrain, get the size of the basement, surrounded by the version of the building, constructed to practice pool. The open field wants to draw a long stream, picking the scenery all stay miscellaneous trees. ...... moon yin Qing Wei, house around the plum Yu planted bamboo; seems to be more interesting, more into the deep feelings. The two or three curved all spring hide, one or two places can be summer avoidance." Visible, these three garden sites are concerned about the use of natural environments, mountains around the water around, the quiet curves have feelings, can reflect the "since the natural interest, do not bother the work of the people," the characteristics of the garden landscape, which is in line with Chinese feng shui thought of the pursuit of the ideal environment. The book "Garden Metallurgy" "phase of the ground" many methods derived from the feng shui theory of "phase of the ground" methods, such as "Buzhu", "thousands of mountain ranges, ten thousand ravines flow green ", "open the pool base mountain" and "according to the Pinggangquwu" (similar to the horseshoe-shaped concave land in Feng Shui) and so on.　Ancient Chinese gardeners in the garden site selection (phase of the land) are guided by feng shui ideas. Qing dynasty Qianlong had been in the Yuanmingyuan painting French missionary Korea Ying (P? Pierre Martial) recorded a gardening philosopher Liu Zhou about the garden site imagery narrative: "they first pursue is fresh air, good orientation, fertile land; shallow long foo, flat deep ravine, clear lake, all with good; they hope that there is a mountain to the north can block the wind, the summer attracts the wind, the wind, the wind, the wind, the wind, the wind. mountain to the north to keep out the wind, to invite coolness in summer, to have springs and veins pouring down, to have a pleasing closure to the distant view of the sky, and to return the first and last rays of light all the year round." On the other hand, it clearly shows the aesthetic idea of Feng Shui. Qing Dynasty archives recorded that generations of architects working in the royal building planning and design affairs of the architectural family style Lei, every palace, mausoleums and other design planning, are to be sent with the feng shui officials to the field phase degree of feng shui, but also to draw special feng shui terrain painting samples. Beijing in the Qing Dynasty, the famous Xiangshan Jingyi Garden, Yuquanshan Jingmingyuan, Wanshoushan Qingyi Garden (now Summer Palace), Changchunyuan and Yuanmingyuan and other large-scale royal gardens, is obviously to the idea of feng shui as the site selection (phase of the ground) mechanism. Similar examples in the construction of private gardens are numerous, because most of the private gardens is a garden, the house is one, private gardens site selection by feng shui ideas of course.　As seen above, the location of traditional Chinese gardens is influenced and guided by Feng Shui ideas. In the past, people on the evaluation and study of traditional Chinese garden theory, mostly from the perspective of poetry and painting, borrowed from the ancient painting theory, many of the theory of literature; and rarely take the theory of feng shui, so as not to fully explain the traditional garden art of gardening.
