According to relevant data, the bad attitude of early delivery of small meals and wrong meals induced customers to return orders and falsely deliver goods (click to confirm delivery but did not actually deliver goods). Merchants eat slowly, traffic accidents are bad, the system did not send a rejection notice to customers to modify the delivery time, requiring delivery time to be delivered to the store illegally within the delivery time specified by the system. Hummingbird crowdsourcing is the latest distribution service brand app, which creates an instant distribution logistics form and officially goes into operation on 20 15 10. Advocate the concept of crowdsourcing, everyone can be a distributor and can work part-time.
