His paintings inherited the style and characteristics of Wu Pai's literati paintings, created on the basis of sketching, learned from foreign teachers, gained spiritual source, and embodied the spiritual realm of the other in his paintings. International academic circles say that Zhang Hong's landscape painting is exquisite and rare in the world. He once climbed a mountain to draw a bird's eye view, which was even more rare at that time. The overall picture of his paintings is profound and elegant, the rocks are hard to knock, and the water is clear and trickling down, which injects spirituality into calligraphy and painting and makes people feel separated from the world. His landscape paintings set off an extraordinary atmosphere by rendering, giving people an immersive feeling, as if they were in a picture scroll. The picture is fresh and elegant, the atmosphere is harmonious, the mountains and peaks are strange, the ancient trees are dense, the breeze is flying, and the artistic conception is ethereal and clear.
