Suiyang county in Zunyi, Guizhou province, is famous for its natural karst landform scenery — the result of unique geographic conditions.
Shuanghe Cave, the longest karst cave in Asia, is one of those attractions, located at the Shier Beihou Scenic Spot in the county, which has carried out a variety of tourism activities, including spelunking, abseiling, climbing and concerts to meet the diverse needs of visitors.
During a music week, which kicked off on April 30, the scenic spot saw a tourist volume rise to 35,000, with revenue reaching 5 million yuan ($708,000).
