This painting spectrum includes more than 50 works by Mr. Yu Feiyan, whose painting advocates the ancient rather than the ancient, and pays more attention to the cultivation of the teacher. It can reproduce the instantaneous dynamic characteristics of a grass and a leaf, rather than the rigidity of a still life. In addition to learning scroll painting, he also learned the simple decorative techniques of Song pure silk. Yu's brushwork assimilated calligraphic methods, while his color application emphasized delicate elegance and luminous vibrancy, conveying both the form and spirit of his subjects. He rejected excessive craftsmanship that sacrificed the expressive vitality of brushstrokes and the painting's overarching essence. Unbound by convention, Yu boldly innovated—his ink-outline orchids, bamboos, and narcissuses are vividly lifelike, exuding refined grace, while his peonies uniquely combine spring blossoms, summer foliage, and autumn stems on a single branch. Rooted in reality yet transcending it, his art achieves perfect harmony with nature.
