What values did the German film "The Eavesdropping Storm" set forth?

The last ten minutes of the eavesdropping storm is a milestone, just like all the stormy waves silently impacting the dam. When the Berlin Wall fell, Weissler, who was demoted, worked as a letter opener in the basement for four years and then walked back to the ground. The Berlin Wall fell, a new drama began, officials were still old, and national treasure writers could not create new works. He was surprised that when all his peers were monitored, he was not. The official told him with a strange expression, "Your monitoring level is the highest, and every corner of your house is covered with eavesdropping equipment for 24 hours." When the Berlin Wall fell, the author went into the museum for the aged to check his monitoring report. He saw another "script" of his life in the report in the hill-like archives, and also saw the "script author": agent code HGW XX/7. I saw the fingerprints accidentally left on the report paper by the defectors of the old system, like the signature of an angel. When the Berlin Wall fell, the writer drove to find his guardian angel in the dark ages. He watched the bald middle-aged handyman drag his car from door to door to deliver newspapers and letters and walk quietly through the street. Two years later, the author's new book was published. Weissler dragged the car past the big poster and walked into the bookstore. He saw the Sonata for Good People, and he saw the words "Dedicated to HGW XX/7" on the title page. He smiled with the book for half a second and bought the expensive book. So one day in the 1990 s, in a bookstore in Berlin, when the cashier asked a middle-aged man in plain clothes, "Are you going to give someone Bao Shu?" The street messenger with big eyes said calmly and proudly, "No, this is for me." The achievement of a lifetime, the secret in the sun, makes the viewer sad and tearful.
