Special Mention
特别提醒

The most distinguished features of the buildings in the ancient city are "river aligned" and"mountain oriented" .The houses are mostly set by a river，usually parallel to the watercourse and long with roofs of tiles,the front facing the street as shops and the rear hanging over water like towers.
古城里建筑多沿水而筑，随着水势而构成一条与河流并行的瓦屋长廊，临街为铺，临河为楼，前铺后楼。

Apart from waters，the mountain topography also the orientation. Some houses cling firmly to the rising land and go up，others overhang from high above.They vary in size and placement along the streets，one behind another in layers over layers.
古城的建筑除了顺水而筑外，还依山向建。沿街建筑囚山势起伏而变化，有的房屋附势竞上，有的则是居高临下，顺街而上，房屋错落，层层叠叠。
