The main body of Longwei is a hall, which is an extension of two halls and two horizontal halls and three halls and two horizontal halls. It built a half-moon paddock at the back of the hall, connected with the horizontal roofs on both sides, and surrounded the main room in the middle. There are two halls with two horizontal dragons and one enclosed dragon, three halls with two horizontal dragons and one enclosed dragon, two enclosed dragons with four horizontal dragons, six horizontal dragons and three enclosed dragons, and some have as many as five enclosed dragons.
The surrounding dragon houses are mostly built on the mountain, and the whole house spans between the hillside and the flat, forming a double arch curve with low front and high back, low sides and high middle. The buildings are stacked on top of each other, and looking forward from the top of the house is a broad prospect. Looking down from a height, the front is the half moon pool, and the back is Longwei. Two semicircles are combined to surround the main room, forming a circular whole.
The central axis room in the paddock is Longtang, opposite to the ancestral hall in Shangtang, which is the storage hall of public goods. There is a half-moon space between the enclosure and the purlin, which is called "flower head" or "melting tire" The "tire-melting" slope is used for planting flowers and trees or paving with gravel and pebbles, rather than paving with stones or concrete, which means that the dragon god is not blocked but turned into a tire, and it is a land of feng shui.
The origin of Hakka Dragon House;
From the Jin Dynasty to the Tang and Song Dynasties, due to war and famine, the Han people in the Central Plains of the Yellow River Basin were forced to move south, and after five great migrations, they were exiled to the south. Because the flat land has been inhabited, we have to move to mountainous or hilly areas.
When registering the household registration for these immigrants, local officials established themselves as "Hakkas" and called them "Hakka" and "Hakka", which is the origin of Hakka appellation. In order to prevent the invasion of foreign enemies and wild animals, most Hakkas live in groups, forming enclosed houses, enclosed houses, Zoumalou, Wufenglou, Tulou, Sijiaolou and Diaolou. Among them, the enclosed houses are the most existing and the most famous, and they are the concentrated embodiment of Hakka architectural culture.
Meizhou Wei Long House began in the Tang and Song Dynasties and prevailed in the Ming and Qing Dynasties. Hakkas adopt the most advanced beam-lifting and bucket-crossing technology in Central Plains architecture technology, and choose hilly areas or sloping fields to build Longweiwu. The main structure is "one entrance, three halls, two compartments and one enclosure". Most of them live in remote mountainous areas. In order to prevent the harassment of thieves and the rejection of local people, camp-style houses were built.
