The whole film is unified in a clear blue, and it is leisurely in melancholy. This is the temperament of the two little heroes in the film. A large number of long shots and fixed seats tell the story of the two little heroes' travels calmly. The movement of the lens often carries the rhythm of poetry, just like opening a "scattered perspective" of China landscape scroll for the audience. Ritual scenes, as well as some lines of poetry reading test, make the audience seem to be watching a deep and dignified Greek classical drama. Open roads, unmanned stations, and speeding trains are constantly appearing, and I appreciate the sadness and loneliness on the way with my wandering brothers and sisters.
