Holding a thick and clear bird song is like holding the fruitful fruits of decades of ecological poetry and ecological poetics by Hua Hai. Fruit is not less than a child's heartbeat, not less than the global ecological concept. We plant the fruits of nature and grow the fruits of spirit, just as we plant the wind and harvest the scenery.
Bird song itself is an open book and a map of the soul. Our body and mind need natural feeding all the time. Every natural fact symbolizes some kind of spiritual fact. Every landscape in nature corresponds to a certain state of mind, and the state of mind can only be presented by treating the natural landscape as a painting or a poem.
