As we drove through Wuyishan National Forest Park, I stumbled upon this little stream.the water is extremely pure,the trees and the blue sky cast their reflections on the water,sun.the sunlight brightened the water plants at the bottom of the stream, suddenly,a leaf drifted down,then a soft layer of ripples spread across the calm water surface. all of these things make it look like a green and vivid painting in spring,yeah,it's a tender gift from winter to spring.
