Guiyang: China's Summer Retreat and a Poetic Karst Mountain City Welcome to Guiyang, the capital of Guizhou Province, widely known as China's "Summer Capital." Set amid lush mountains and dramatic karst landscapes, Guiyang is not only the main gateway to Guizhou's natural wonders, but also a vibrant and livable modern city in its own right. For international visitors, Guiyang offers a unique dual experience. On one hand, you can enjoy its cool, comfortable climate while exploring ancient towns, green valleys, and limestone scenery shaped by karst geology. On the other, you'll feel the pulse of a forward-looking metropolis - often called China's "Big Data Capital" - where innovation, night markets, and neon-lit streets blend seamlessly with a bold local food culture famous for its addictive sour-and-spicy flavors.
