徽州古村落中“水口”位于村庄整体建筑空间序列的开端，“水口者，一方众水所总出处也”。古代风水师缪希雍早就作出这一定义，大体点明了水口在村落建筑格局的方位，徽州古村落水中一般设在下水出口处。因受风水学说“山发人丁，水聚财”之影响，故要求水口地形要“锁闭”状 The “sluice gate” in the ancient village of Huizhou is located at the beginning of the village’s overall architectural space sequence. “The water outlets are also the main sources of water for all parties.” The ancient feng shui master Xi Xi’e made this definition long ago, roughly pointing out the position of the outlets in the village’s architectural pattern, and the Huizhou ancient villages’ water is generally located at the outlet of the sewage. Due to the influence of Feng Shui theory, “the mountain sends people Ding, water gathers money”, it is required that the shape of the outlet must be “locked up”
