Guiyang: Sour Fish Soup, the Heart of Miao and Dong Flavors

In the mountainous city of Guiyang, capital of China’s Guizhou province, one dish stands out as a cultural emblem: sour fish soup (酸汤鱼). This iconic dish, simmered in a tangy broth made from fermented rice or tomatoes, showcases the bold flavors of the Miao and Dong ethnic groups. For those unfamiliar with Chinese cuisine, think of it as the "sourdough" of Guizhou—naturally fermented, deeply flavorful, and uniquely regional.

The soup’s sourness comes from xiaosuan (small sour), a red fermented chili paste, or daosuan (big sour), a milder tomato-based version. Locals often compare its balance of acidity and spice to the tangy heat of Indian dal or Mexican pozole, but with a distinct Chinese twist. Fresh river fish (like carp) is added, along with pickled vegetables and tofu, creating a hearty yet refreshing meal.

Beyond taste, the dish reflects Guizhou’s culinary philosophy: using fermentation to preserve freshness in its humid climate. Sour fish soup is usually seen as a main dish at Miao and Dong gatherings, symbolizing community and tradition. Visitors to Guiyang often find it a gateway to deeper cultural flavors—like tasting Italy’s risotto or Morocco’s harira, it’s both a meal and a story.

For food explorers, Guiyang’s sour fish soup is a must-try, a small bowl of history, spice, and mountain hospitality.
