The house structure of Longwei is generally "three halls and two horizontal Yi Long Wai". There are dragon hall, flower bed, upper hall, middle hall, lower hall, daily hall (patio), north and south hall, flower hall, porch, back corridor, hand corridor, main hall, horizontal room, dragon enclosure room, bathroom and kitchen. There is a gate in the middle of the house and small doors (side doors) on both sides. Enter the horizontal house along the left and right side doors, and then extend backward from the horizontal houses on both sides into a half-moon shape. Between the back hall and the enclosure, a hemispherical slope higher than the foundation of the front house should be built, commonly known as "flower tire" The flower bed is covered with pebbles or grass or flowers, similar to the back garden. There is a spacious doorway in front of the house, and a half-moon pond is dug in front of it. Tree species are behind the enclosure, commonly known as "wind enclosure trees". Both urban and rural buildings are covered with lime brick walls. The vast majority of dragon houses are single dragons, and there are also double dragons and many dragons.
The buildings around Longzhai have the following characteristics: First, pay attention to geomantic omen. General buildings are built in the foothills near mountains and rivers. The choice of the homestead is that the mountains are vigorous, the foothills are flat and spacious, surrounded by green water, and the mountains are like a case, and the peaks in the distance are pen-shaped. The general building orientation is to sit north facing south or west facing east. In summer, the south wind blows the window to avoid the west, and in winter, the lee is sunny and the lighting is sufficient.
The second is about symmetry. Buildings generally take the north-south meridian as the central axis, and the east and west sides are symmetrical, with low front and high back, clear primary and secondary, and orderly position. Based on the longitudinal axis of purlin, the surrounding dragon is higher than the upper hall, the upper hall is higher than nave, and nave is higher than the lower hall. The horizontal houses on both sides are perpendicular to the plane of purlin, and adopt a symmetrical quadrangle structure, which overlaps front, back, left and right. The pond in front of the house and the dragon group behind purlin form an Atai pool-shaped whole.
The third is to pay attention to collocation. There is a half-moon lake in front, which has the functions of storing water, raising fish, preventing fire and fighting drought. There is a front door on the periphery, a bucket in front of the door and a fence along the door. There is a spacious doorway at the main entrance, which is used to bask in the valley, enjoy the cool and practice martial arts. Behind Menping is the main hall, which is divided into upper, middle and lower floors. There are altars and ancestral temples in the upper hall, with swords, spears, halberds, lion drums, gongs and cymbals on both sides. The nave is the main place for ethnic discussions and banquets. The hall next door is the place where the invited bronze drum octave class sets up the music scene and the bearers set up their seats during weddings, funerals and celebrations. The rooms on both sides of the upper and lower halls are called principal rooms, where parents and the eldest son of the largest room live. Hakkas have a saying that "the eldest son does not move". The halls on the left and right sides of the upper and lower halls are called the South Hall and the North Hall, which are reception rooms. The house near the horizontal house between the middle hall and the lower hall is called the living room. There is a patio, a flower pond and a rockery at the door, which is a place to read and write. There is a house on the left and right of the main hall, called pillow room, with complete facilities such as bedroom, kitchen, well and utility room. The outdoor part between the main hall and the pillow house is called patio, which is used for ventilation, lighting and drainage, and as a fire lane in case of fire.
The fourth is to pay attention to decoration. The walls of the hall are decorated with profound paintings, such as Farming in the Spring Suburb, Reading at Night with Lights Burning, Mulan Joining the Army and so on. The movable screen in the hall is an exquisite carving art; There is a leaking window in the corridor connected to the hall; Planting flowers and evergreen trees in patios and flower heads; There are all kinds of carvings and colorful paintings on the column beam bucket arch; Most eaves are carved with hardwood into the first beast pattern; There are stone lions and memorial archways outside the gate.
