Firms based at the Yiwu Bonded Logistics Center in Yiwu, Zhejiang province were among the most eager participants of this year's "618" online shopping festival.

The festival was created by JD, China's second-largest e-commerce platform by gross merchandise volume, to celebrate its founding date of June 18. Online retailers at JD and many other platforms tend to offer massive discounts on the days surrounding June 18 every year.

Data shows that the Yiwu Bonded Logistics Center sent out goods on 2.3 million purchase orders between June 1 and 18 this year, a nearly 20 percent increase from the previous year. The peak day in the center fell on June 1, which saw the outbound delivery of goods for 600,000 purchase orders.
