Guizhou Province's Xiazi Town, also known as 'Chinese Pepper City,' has become a significant economic hub in China, dealing with 750,000 tons of chili peppers annually. Initially a humble, disorganized trading post, it has grown into a professional market with infrastructure like big data, financial, logistics, and inspection centers. Covering 31 hectares, it transacted 300,000 tons and generated USD 1 billion in 2022. The 'pepper city's' pepper index is crucial for setting prices in the market, with other regions and markets following the prices of Guizhou chili peppers.
