The challenging terrain and limited transport options meant that transporting tea from when it was picked up to the airport was a prolonged affair. This not only affected the tea's freshness but also delayed its arrival in the market.
Two cargo drones are now operating for the spring tea run, handling an average of two tons daily. "This drone has a standard payload of 20 kilograms and a flight duration of 20 to 30 minutes," Cheng added.
