One of Yunnan's famous "18 Oddities" says, "Flowers here are sold by the kilo." Jason had a visit at the Dounan Flower Market in Chenggong district in Kunming, down in southwestern China. The Asia's largest fresh-cut flower market supplies seven out of every 10 flowers sold in China. Every day, more than 1,600 types of flowers are traded here, with annual sales topping 10 billion stems. Dounan's success isn't just luck. Beyond high-quality flowers and hardworking farmers, digital technology has transformed the industry.
