Project Introduction:

Dali Haidong Huanglongshan Tunnel is Yunnan's first intelligent digital scenic tunnel. The dome and both walls feature 3D-printed panoramas of Dali's natural scenery and cultural history. Upon entering the tunnel, the dome is filled with blue skies and white clouds through 3D spraying technology, while both sides are adorned with giant mural scrolls of Dali's natural landscapes and cultural attractions, including Cangshan Mountain and Erhai Lake, the moods of wind, flowers, snow, and moon, and fishing boats at sunset. Visitors can enjoy the Dali scenery and cultural sites, the large murals, Cangshan Mountain, Erhai Lake, and the changing seasons, creating the sensation of 'traveling through the tunnel while immersing in the scenery.' The painted images inside the tunnel use a special environmentally friendly water-based paint, which is corrosion-resistant, fireproof, waterproof, and peel-resistant.
