Translation:Manshu — Chapter 4
“ Architecture Original Translation 凡人家所居,皆依傍四山,上棟下宇,悉與漢同,惟東西南北,不取周正耳。 Regarding the ordinary people's houses, they are always constructed similarly to four ‘山’ characters, with a high ridgepole and lower eaves. They are very similar to Han Chinese houses, but always face north-south-east-west and as such do not properly accord with their endemic environs. [18] 別置倉舍,有欄檻,腳高數丈,雲避田鼠也,上閣如車蓋狀。 Barns are separate to residences, and are fenced-off. They are a few zhàng (ie. about 10 meters) in height, the upper portion being resistant to rodents, and resembling vehicles in their manner of covering. ”
