Why siberia is called land of the dead?

Siberia is not commonly referred to as the "land of the dead." It is a vast region in northern Asia that spans several countries, including Russia, Kazakhstan, and parts of Mongolia and China. While Siberia has a cold climate and can be harsh and inhospitable, it is home to a diverse range of ecosystems, including forests, tundra, and steppes, and is inhabited by a variety of ethnic groups and cultures.
