Wu Nan's works always carry a sense of spiritual tranquility and serenity. He enjoys expressing transcendence and subtlety through impressions of nature. Wu often employs little girls and puppies as subjects of his works, showing his understanding of the village life in China and creating exquisitely an imaginary world that blends illusions and reality. The painting depicts a little girl and a puppy in a spacious cave full of vines and grass: the little girl sits in the quiet cave, while her puppy companion turns to look at her; the girl's gaze is however fixed on the faraway peaks hidden in the clouds. The artist successfully used the vast, deep cavern, the little girl, the puppy and the far peaks to create a profound and serene imagery. Another interesting special feature of Wu is his habit of mounting his Chinese scenery paintings on oil canvas frames. To summarize, the artist incorporates his keen observations and experiences in his sketches, depicting the mountains and waters in an artistic imaginary form, creating the sublime image from his mind.
