This film is also unique in art. All the scenes were shot on location in Salzburg. The director and designer boldly used helicopter shooting methods, using long distance shots from a high altitude. Taking a panoramic view of the foothills of the Alps and Salzburg, and then moving vertically and horizontally, descending sharply, until close-ups and half-lengths of the characters are taken, effectively highlighting the inner state of the characters, making the film full of poetry and painting.
