___ Yuanmingyuan Park—Beijing’s Old Summer Palace—sprawls across 2.2 square kilometers, destroyed by invading forces in 1860, its ruins are a quiet monument to the Qing Dynasty’s splendor. Ten million visitors a year wander its paths, hungry to connect with that lost past. In August 2024, we launched Chrono Craft: a fleet of 20-seat augmented reality immersive buses that don’t just tour the park—they transform it into a living, shared theater.
