Lidung Jelo (also known as Lidong Jelor) was an ancient remote Kenyah's longhouse settlement in the mountainous interior located by the Plieran river bank, Belaga division of Sarawak.

There are many local fruit trees like durian, alim, terap, rambutan and langsat which still grows wild in these old settlement areas.

First of all, they desired peace, or at any rate less warfare, and it was possible to convince them that this result might be achieved by pointing to other districts such as the Rejang and Jenalong (Tubau), with whose affairs they had some acquaintance.

In those days the Kenyahs buried their dead in hollow tree-trunks twenty to thirty feet high, on which they craved patterns called 'uduk'.

During our recent expedition to the village site in Lidung Jelo, Usun Apau Plieran, we found more than three upright piles (a real hardwood called 'kayu merang') of old houses in a straight line still remained in the ground.
