In the image, the settlement on the left is the lower Dawu settlement, also known as the little mountain alley of lower Dawu. It is located southwest of Wutai village, on the flat platform on the right bank of the upper reaches of north Ailiao River, with an altitude of about 460 meters. The name “little mountain” may have come from the terrain where the settlement is located. Shiderao, or as it is transliterated as "Delau", is the main settlement. In the 6th year of Taisho (1917), due to disputes with other communities and got severely criticized by the chief, the settlement was formed by relocating the Wutai community. There were only 10 households in the 6th year of the Showa era (1931).
The settlement on the right is upper Dawu, also known as Dongchuan Alley. It faces Little Mountain Alley across the stream. The settlement is distributed on a flat platform with an elevation of about 500 meters. It got its name from being located on the east bank of the stream. In the 6th year of the Showa era (1931), there were in total 50 households with 270 people. It was the settlement closest to the central mountain range at that time, and traveling in and out was extremely inconvenient.
