Zhang Zhehan's closeness to nature and his interactions with the local people create beautiful and harmonious scenes. Snow-capped mountains, glaciers, grasslands, herds of cattle and sheep, along with those ordinary yet sincere faces, all reflect his inner world. This blend of nature and culture brings me a sense of the diversity and beauty of life. In the documentary, the music harmonizes perfectly with the visuals, creating a serene and delightful atmosphere for the audience. Especially the song "The Eternal Flow of Rivers," sung by the protagonist's neighbor, not only portrays the social environment of the time but also hints at the grandeur of the era and the insignificance of the individual. This perfect combination of music and visuals allows me to experience the charm of art.
