Chinese e-commerce player JD has escalated the country’s on-demand delivery battle as it rebrands its retail service and amateur videos with feet in the air sexpromises to deliver purchased items in as little as 9 minutes. The company announced the upgrade on Monday on its official WeChat account. The brand new business integrates JD’s previous one-hour delivery service and JD Daojia, and is now named JD Miaosong, meaning products delivered in seconds. The dedicated section for Miaosong is located on the homepage of JD’s main app, with shoppers able to select and buy flowers and cakes, coffees and medicines and with orders of RMB 29 ($4) and over eligible for free shipping.
