As the Zomi lacked a formal writing system in the past, the story of Tedim mostly depends on oral tradition.

Establishment of Tedim is ascribed to Gui Mang II, a powerful prince from the then ruling Guite family in the region (c. 1600).

At the time of Mang Suum II, son of Pum Go, the allied force of the Pawihangs began their advance in the region and attacked Tedim.

The ranges of Hills of Thangmual include Kennedy's Peak, Lunglenkawl, the Rih Bual, the Hausapi, the Gullu Mual, the Zangmualli, the Tuikangpi, the Suangsuang, and the Lentangmual.

There are dams, caves, peaks, and other attractions, including Lennupa Mual, the Twin Fairy Hill and other historic sites.
