Forty years ago, Yiwu was a small agricultural county in the middle of Zhejiang Province. Since China's reform and opening-up, the county has seized any opportunities to continuously develop and innovate its economy. After 40 years of development, Yiwu, now a county-level city, has been well-known as the world's largest wholesale market for daily commodities. (Xinhua/Tan Jin)
