Because the flat land has been inhabited, we have to move to mountainous or hilly areas, so there is a saying that "every mountain must have guests, and there are no guests to live in."
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 Dragon House, Zouma House, Wufeng House, Shiwei House and Sijiaolou. Among them, Dragon House is the largest and most famous one in existence, and it is a concentrated expression of Hakka architectural culture.
Meizhou Wei Long House began in the Tang and Song Dynasties and prevailed in the Ming and Qing Dynasties.
Hakkas adopted the most advanced combination technology of lifting beams and piercing buckets in the architectural technology of the Han nationality in Central Plains, and chose 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 crowding out of local people, there are two forms of camp-style houses: one is brick structure.
2. Special adobe structure: lime is mixed into the soil, glutinous rice and egg white are used as thickeners, bamboo chips and wooden strips are used as bones and muscles, and a rammed earth building with a wall thickness of 1 m and a height of15m is built.
Ordinary pens cover an area of 8 mu, 10 mu, and large pens cover an area of more than 30 mu. It often takes five years, ten years or even longer to build a complete enclosure house.
Longwei is a huge fortress of Hakkas.
There are many bedrooms, kitchens, large and small halls and living facilities such as wells, pigsty, henhouse, toilet and warehouse. In the house, form a self-sufficient and happy social group.
