            "description": " Multiple authors describe defensive structures surrounding Hmong settlements: 'The Miao settlement is called “chai” (Illus. 12, 13), built generally against a mountainside or along a river, without any uniform appearance. The chai wall is made of earth or stone slabs, and there is no definite number of gates. The streets of a chai zigzag up and down, with tiny alleys on both sides. In each alley there are a few families. The alleys are interconnected. Without a guide one can get lost once inside a chai; turning right and left, one will be unable to find an exit. Chinese passing through a Miao chai often cannot find a single Miao, because they have gone into hiding in small alleys, barring the doors and refusing to come out. The Miao chais are not located along lines of communication but in the deep mountains and valleys accessible only by small paths. Although visible at a distance, they often cannot be reached. Without modern arms, they cannot be easily taken. For the last few hundred years continuous Miao unrest in western Hunan may be largely related to the fact that their chais were easy to defend and difficult to capture.' §REF§Ling, Shun-sheng, Yifu Ruey, and Lien-en Tsao 1947. “Report On An Investigation Of The Miao Of Western Hunan”, 59§REF§ 'There were formerly many fortified places called in Chinese chai tzŭ where groups of houses were clustered together for protection. This is indicated by the names of places such as Wang Wu Chai and by the frequent references to fortified places in the legends. To-day there [Page 23] are none to be found. One explanation given by Ch'uan Miao friends is that the danger of fire was too great so that people no longer built their houses so close together. There are two other possible reasons. One is that the Chinese destroyed the strongholds in war and to prevent future rebellions, and the other is that there is no longer danger of raids and attacks from the Lolos. Chinese histories actually mention the destruction of the strongholds' §REF§Graham, David Crockett 1937. “Customs Of The Ch’Uan Miao”, 22§REF§ We have assumed mortared stone walls for the time being."
