The overall lens language, scheduling, composition and mirror transportation of Salesman are basically similar to Farhadi's A Farewell, but slightly inferior in overall viewing rhythm and impact. It can be seen that the overall style of director Fahati should be based on new realistic narration, and the pursuit of life, the grasp and application of details and the adjustment of actors' performances are all based on realism. Scheduling and mirror transportation are very smooth, without obvious stylization and skillful means. Only occasionally use a hand-held lens to add realism to the story. What I admire most is the director's polishing of the script. No matter "A Farewell" or "Salesman", the script layout, the establishment of characters and the story line are all very sophisticated, and will not appear too fragmented and become a rambling narrative; Nor can it simplify or hide the establishment of characters' motives. On the whole, his grasp of stories and conflicts is very friendly to the audience, and there will be no sense of embarrassment as director Cheng Er said in Romance of Death, "This is a movie for people in the next century." From this perspective, we can also see that the director is a person who can speak or argue better than acting. He prefers to export a value rather than an emotion.
