Mount Qingcheng and the Dujiangyan, a UNESCO World Heritage site in China, combine a sacred Taoist mountain with an ancient irrigation marvel. Mount Qingcheng’s lush peaks host historic temples, reflecting its status as a cradle of Taoism, while the Dujiangyan system, built over 2,000 years ago, showcases ingenious engineering that tamed floods and irrigated fields. Together, they represent a harmonious blend of nature, spirituality, and human innovation.
