Which one is free between Hummingbird’s preferred and exclusive delivery?

Special delivery.

1. Hummingbird Selection and Special Delivery target different groups of riders. Hummingbird Special Delivery is aimed at ordinary part-time riders. As long as you register for Hummingbird Crowdsourcing, you can join the platform to receive orders, while Hummingbird Selection needs to go through Filter through layers.

2. The assessment mechanism is different. Hummingbird Preferred riders have an assessment mechanism for online time and afternoon and evening peak hours, while Express riders have free working hours and do not need platform assessment unless there is a timeout.
