In the ’Sketches of China and the Chinese’, Auguste Borget describes: ’This part of the valley has only a narrow opening towards the seashore. In the middle of this little gorge stands a large mass of rock. On the summit they formed a little canal, and placing at each extremity a pipe formed of bamboo, have thus constructed an aqueduct to convey the water across the valley, and so fertilised places which, without such an expedient, had been condemned to eternal sterility.’奧古斯特‧波塞爾在《中國及中國人素描集》中，對這幅畫有如下的描述：「此部分山谷，僅有一個狹窄的出口可通向海邊，峽口有一巨石，在岡頂的兩邊，有一條引水道，由一條橫亙於巨石上的竹製導水管接連，把水導引到一塊荒瘠的土地，作灌溉之用。」
