황산에서 흡현으로 가는 도중에는 "고건장랑(古建長廊)"이라는 칭호를 가지고 있는 잠구(潛口) 명대(明代)의 민가는 걸출한 건축물이다. 황산 온천구를 지나 약 60키로쯤 되는 자하봉(紫霞峰)의 아래에 있으므로 "자하산장(紫霞山庄)"이라고도 하며 국가 중점문물보호단위이다. 전체 면적이 16000㎡이며 부근에는 10개의 전형적인 명대(明代)의 건축이 있는데 오늘날의 독특한 풍격의 명대산장(明代山庄)을 형성하고 있다. 이 열개의 명대 건축은 음수교(蔭秀橋), 석패방(石牌坊), 선화정(善化亭), 낙선당(樂善堂), 조문청(曺門廳), 방관전택(方觀田宅), 방문태택(方文泰宅), 소설흔택(蘇雪痕宅) 등이 있다.
On the way from Mt. Huangshan to downtown Huangshan city, Tunxi, there are a lot of old buildings, and this section of the road is called the long corridor of old buildings. Of these buildings, the Qian Kou Residence is a particularly remarkable one. Located in the Huizhou District, Huangshan City, Anhui Province, the Qian Kou Residence has another name, Zixia Mountain Villa because it lies at the foot of Mt. Zixia, which is 60 kilometers (about 37 miles) away from Mt. Huangshan. One architectural expert has said that to visit imperial palaces, you should go to Beijing; whereas to see old residences, you should go to Qian Kou. The Qian Kou Residence is an epitome of residences of the Ming Dynasty (1368 - 1644). In 1980s, in order to protect the old residences, the government disassembled the ten most valuable old buildings of Ming Dynasty (1368 - 1644) out of hundreds of old buildings from neighboring area and moved them to Qian Kou. The buildings were then reassembled in accordance with their original structures and appearances. Thus, the unique Qian Kou Residence was formed. These ten old buildings include three ancestral temples, four residences, one stone memorial arch, one arch bridge and one pavilion. The components of this architectural complex are situated in accordance with Mt. Zixia and show people the entire garden-style residence in a harmonious manner, although each of the components has a different background and history.
