First, the basic explanation:
1 refers to ancient or distant people nesting in trees.
2. Still living in seclusion.
Second, the detailed explanation:
1 refers to ancient or distant people nesting in trees. Zhuangzi stole the foot and said, "In ancient times, there were many animals and few people, so they all lived in nests to avoid them." China's "Natural History" Volume III: "The south is a nest, and the north is a cave to avoid cold and heat." Tang Du Fu's poem "Five Dishes": "A good bird doesn't fly wildly, but a savage lives in a half nest."
2. Still living in seclusion.
Liu Mingji's "Two Rhymes and Nine Days Meeting at the Stone End": "It is useless to overcome difficulties, and the nest is everywhere to suppress Cui Wei." Ming and Xu Sanling's Gui Ji Yi: "It's just that one day in the nest, the spine is sad, outdoor birds can be found, and the swallow in front of the hall has gone."
Third, related research:
Wowu, namely Ganlan House, is an architectural style invented by Baiyue tribe in ancient south, that is, a house built on a wooden (bamboo) column underframe above the ground. The earliest dry fence building discovered by archaeology is Hemudu dry fence building, which was popular in the jujube-refusing residential area of Baiyue tribe in the south in ancient times.
This kind of building is mainly made of bamboo and wood, and it is mainly a two-story building. The lower floor is full of animals and sundries, and people live on the upper floor. Dry-column buildings can resist earthquakes and so on. China's ancient history books also have names such as Gan Lan, Gan Lan, Gaolan, Gelan and Gelan, which may be transliteration from the ancient Vietnamese.
In addition, grid dwelling, nest dwelling, etc. What is mentioned in the general literature generally refers to the dry column building. This kind of imitation and nesting "high table civil building" is the early "dry column building" In the ancient literature of China, there is a legend of nesting. Such as "Mencius Teng Wengong": "The bottom is the nest, and the top is the camp".
It can be seen that nesting has obvious advantages in avoiding hot and humid environment, staying away from insects and beasts, and taking local materials. This residential form skillfully uses the vertical space distance as the boundary, which is a creation of human beings in the process of adapting to the environment.
Different from the cave dwelling mode popular in the north, the humid and rainy climate in the south and the dense natural geographical conditions in the mountains naturally gave birth to the living mode of "taking trees as nests" in Yunnan, Guizhou and South China. "Book of Rites" said: "The first king had no palace, lived in the camp cave in winter and lived in the cave in summer." It can be seen that nests and caves are not completely separated by region.
