The wall at the entrance of the courtyard

There are two special functions in the architectural form of siheyuan. In the old Beijing courtyard house, no matter how many courtyards it is, even if it is a single courtyard, the street door is opened in the southeast direction. If we say the reason, we have to start from Beijing's geographic location, Beijing is surrounded by mountains on three sides, southwest, west, northwest, north, northeast are in the Yanshan Mountain Range surrounded by. If you look at the topographical map, Beijing is a city built on the side of a mountain. The mountains to the west and north prevent cold air from Inner Mongolia and northern China from reaching the mountains, while the warm and humid air from the south and southeast coasts often brings warm and humid air currents to Beijing. If we look at the five elements of the I Ching, the southeast is Xun position, the five elements of wood, the attribute of wind, the main message affairs. From this direction, it is more favorable for the owner of the house to live in peace than the dryness of the fire in the south and the vibration of the wood in the east. So from this geographical environment and the five elements, it is not difficult to see that the whole courtyard is most conducive to open the door to the direction of the southeast. In this way, the courtyard with the door open in the southeast will have "qi" directed at the south wall of the east room. Shadow back wall at this time will play a role in resisting the wind blowing directly against the wall and bring the cold air to the room. And then there is, shadow back wall is the guest into the door looked up the first wall, pay attention to the head to see the joy of the designers tend to use the shadow back wall designed to have a symbol of good luck patterns, to achieve the role of beautification. The city's royal family and some dignitaries' homes, shadow back wall has a lot of glazed tiles to decorate the wall, more in the shadow back wall placed under the tiled fish pots, planting ornamental lotus, Koi in the water, reflecting the sun lotus, quite elaborate.
