The orchid leaves spread gracefully, while the blossoms face upward and downward, exuding a natural charm. The composition is executed with smooth and fluid brushwork, characterized by balanced structure and elegant simplicity. The delicate flowers embody a refined beauty, capturing the orchid’s noble and unpretentious essence.

The painting utilizes varying shades of ink—dense, light, dry, and moist—without the addition of color, emphasizing purity and sophistication. The work conveys the orchid's serene elegance and innate grace, reflecting a sense of timeless refinement.
