Venue

Zhangjiajie is located in the northwestern part of Hunan Province, China, deep in the Wuling Mountains. Established as a prefecture-level city in 1988 for tourism development, it is world-renowned for its quartz sandstone peak forest landscape, often described as "three thousand strange peaks and eight hundred beautiful waters," earning it the reputation of "an enlarged bonsai and a miniature fairyland." As a UNESCO World Natural Heritage Site and one of the world's first Global Geoparks, Zhangjiajie boasts thousands of towering stone peaks, including Tianzi Mountain, Yuanjiajie, Golden Whip Stream, Tianmen Mountain, and Huanglong Cave, which together with seas of clouds and mountain streams form a geological epic of Earth's evolution. The city is also home to 33 ethnic groups, including Tujia, Bai, and Miao, whose farming heritage and folk arts thrive here. Intangible cultural heritage such as the Tujia Baishou Dance, Sangzhi Folk Songs, and Zhangjiajie Yang Opera coexist in this vibrant cultural tapestry, making Zhangjiajie an eco-tourism destination where natural beauty and cultural richness complement each other.
