The Hangzhou West Lake Immersive Night Tour "Gathering at Huanglong · Fate Space," located in the Huanglong Cave Scenic Area (one of the New West Lake Ten Views), was jointly developed by our company and the West Lake Scenic Area. The project preserves the original appearance of Huanglong Cave, uses "Fate" culture as its theme, and integrates natural scenery with digital multimedia technology. The core performance "Mountain Lake Fate Dream" uses digital technologies like 3D mapping interaction combined with culture such as opera to reshape the nightscape. It features interactive installations like "Butterfly Dream of Perfect Fate" and "Wishing Fate Tree," and also incorporates F&B, cultural creativity, and other formats, using XR holographic technology to create the digital human "Long Yue." The project not only successfully activated the commercial value of the traditional scenic spot but also became a practical benchmark for intangible cultural heritage inheritance and cultural confidence.
