I couldn't figure this one out myself, but a baidu search tells us the answer is "画" - or "a painting". 

画中的山是有颜色的，但是水是没有声音的，春天过去，画中的花不会凋谢，人来了，画中的鸟儿也不会飞走

"In a painting, the mountains have color, but the water has no sound. When springtime has passed, the flowers do not wither, and in a painting birds don't fly away."
