This book blooms among green bamboos and strange rocks, and among flowers and bamboo forests. Birds play in the forest, stand on branches, or fall on the ground. Some spread their wings, some look up, and some look back. Comes with different and vivid images, as if it abruptly on top of the golden paper.
