The traditional dwelling is called a "sierranju" () and is covered in the summer with birch bark and in the winter with deer furs. These dwellings have conical forms and are made out of 20 to 30 pine sticks. The dwellings are usually about six meters in diameter and five meters in height. In the centre a fire is placed that serves as a kitchen, as well as a source of lighting. Birch bark is an important raw material in the traditional culture alongside the furs. It serves for the preparation of containers of all types, from the manufacture of cradles to boats. With respect to the reindeer herding of the Evenki, Oroqen and Nanai, which all shared the use of birch bark, it can be said that these cultures are part of a "birch bark" culture.
