[Voiceover] Smart technologies are lending a helping hand to busy tea farmers in east China's Hangzhou City, home to world-renowned West Lake Longjing, or Dragon Well, Tea. At one tea plantation in Longjing Village, a farmer wears an exoskeleton device to assist with his daily tasks. The device is calibrated to his height, weight, and walking pattern to make the physically demanding job of transporting tea leaves and maintaining the plantation, easier. [Soundbite] He Guangxue, Tea farmer: "We need to carry fertilizer up the mountain. With this exoskeleton, it automatically helps lift my legs. It's much less tiring." [Voiceover] Meanwhile, robot dogs navigate steep paths to transport freshly picked tea buds to processing facilities, which has greatly boosted efficiency. And multispectral drones are also being used to monitor tea leaf growth. [Soundbite] Tea farmer: "In the past, we had to check everything manually to see which parts of the field were ready for harvest. But now, it's much easier and faster. We don't have to inspect every single spot; the drone tells us everything at a glance." [Voiceover] As one of China's 10 most famous teas, West Lake Longjing is characterized by its green color, delicate aroma, mellow taste, and beautiful shape.
