Project Background Qiyun Mountain in Anhui Province is an ecological and cultural tourism area characterized by Danxia landforms and Taoist culture, featuring towering peaks and secluded ancient paths. To minimize interference with the pristine landscape and address issues such as complex mountain paths, unstable mobile phone signals leading to tourists getting lost, and limited access to cultural information, a smart guide system deeply integrated with the natural ecology is urgently needed to achieve a seamless service upgrade.
