In Dai dialect, "Dadenghan" is pronounced as "Denghannong", meaning "the golden pond". Legend has it that it used to be a huge swirl formed by the water of the Ruili River. The water from upstream flowed down and conglomerated there, and Dai people thought it was a symbol of "assembling wealth", and named it "the Golden Lake". The watercourse was moved into another route afterwards, and a village was formed there.

Dadenghan Dai Village has a beautiful scenic view and a fine climate. There are trees and green bamboo everywhere; even the Dai residences, which are made of bamboo, are covered by the forests. When the grapefruit come into blossom, the fragrance fills the air. People are fascinated with the fruits, the bamboo, and the umbrella-like Banyan trees.

The Denghan Temple, located deep in the magical forest, was constructed during the Qianlong Period of the Qing Dynasty (1736-1795). The main hall of the temple was constructed over a bamboo mainframe, and the floor of the hall is above the ground level. The roof of the hall is a double-level tilted roof. There are pavilions and cabinets in front of the hall.

In recent years, the Dadenghan Dai Village has become a well-known tourism spot.
