Facing the constant changing new technologies and the world constantly changing human cognition, Wang Xinfu does not blindly follow the trend, but persists in his own belief by learning from his teacher who studied in France before, Mr. Li Youxing to focus on observing objects and emphasizing subjective expression, which is to transform objects into simple decorative color expression. Thus, Wang Xinfu adheres to the principle of manual expression of landscape, specifically speaking, he regards sketching as equal to creation, because this process has accumulated personal perception, judgment, emotion and personality. This "untimely" attitude made him turn to the preference for traditional modernism and try to dig new energy from historical accumulation. Meanwhile, he does not get deeply bogged down in the rigid school painting, but is engaged in painting with new method and idea, stare attentively and discover inner connection between the charm of nature and personal spirit, emphasize exquisiteness of personal perception of the real nature to subjectively recreate the fable rich in feeling, melody, rhythm of the lively nature with brushwork intertwined with expressiveness and abstractness. This is the painter's personal presence, perception and play in the scene of nature, which is also the key to the difference between creating in nature and in the studio.
        Expressive methods of Wang Xinfu's painting are flexible with various style. His landscape is not objective sketching, but let creation rely on sketching, sketching is played subjectively, and is transformed into the result of creation, soaked with personal painting path: the texture highlighted by material nature of  superimposed color; Lines and colors in the picture concentrate and weaken the object expressed. The overall form of the picture and “momentum” of the calligraphy are integrated, while the adhesive coverage of color and lines forms an inseparable state -- not only reflected in play and transformation of aesthetics of nature and “momentum” of the book by the artist, but also reflected in the generation and construction of pure form. Such painting style is difficult to be defined by stylizing, and the formation of its obscure state is exactly the result of  breaking through restrictions and freedom by the painter. Specifically, although his paintings deviate from specific objects and even dilute their attributes, its pursuit of purity and simplicity has become a formal goal -- showing not only freedom from rules and regulations, but also freedom of expression and dynamic passion. In Wang Xinfu’s view, all objects in nature can finally be expressed in a concise and beautiful form, and its microscopic beauty is the most perceptible beauty in the world. This is exactly why he regards painting color as the happiest thing in his sketching/creation, because the generation of color contains expression of personal passion, expression of personal emotion, and presentation of the fluctuation of personal emotion.
