The film Diary of Rabe is aimed at a character, that is, john rabe, a German who established an international security zone during the Nanjing Massacre and protected 250,000 ordinary people. There are not many film and television works about the Nanjing Massacre, each of which has its own limitations to varying degrees. For many years, there have been voices in China calling for a film that can truly reflect historical facts and be understood by the global audience, and a reference example is given-Spielberg's Schindler's List. This classic film, known as "existing as an eternal glory in film history", tells the true historical event that German entrepreneur oskar schindler protected 1200 Jews from being killed by fascists during World War II. When Rabe's Diary was released in Germany, it caused a strong response. People did not discuss the quality of the film on the technical level, but were surprised by Rabe's understanding of the tragic event of the Nanjing Massacre in history-Rabe's diary realized its most authentic wish. When the world film trend focuses on expressing human nature and reflecting on history, Rabe, who saved hundreds of thousands of lives, is once again used to save the common problems of modern people-numbness and forgetfulness. Rabe's Diary is a biographical film, but in the story and details, through some Hollywood-style expressions, it has created a credible, lovely and respectable plump character image. Therefore, what we see in Gao Daquan is not an idolized Rabe, but a Rabe with human weaknesses such as fragility and avoidance. The setting of these plots, whether sad, playful or humorous, not only eased the heavy atmosphere of the film, but also increased the appreciation of the film, and paved the way for Rabe's psychological change from indecision to firm belief. Ambassadors and media will return to Nanjing by boat. Rabe led his colleagues to stand in front of the Japanese gun at the critical moment when the Japanese army wanted to destroy the safe area. The film uses this tense scene to freeze Rabe as the embodiment of justice, and his heroic image is also revived. Rabe's diary also has a theme of redemption. The Japanese officer whose conscience was shaken informed Rabe of the news when he learned that the Japanese army was going to destroy the safe area. Maybe it's because the length and focus of the film are not here. The identity of the Japanese military officer in the film is very vague, and the inducement of his "informer" is not described, so the theme of redemption only plays an embellishment role in the film. Rabe's diary is a film about commemoration. Its most important mission is to arouse more people's attention to the tragedy, to commemorate the compatriots who died in the Holocaust, and to commemorate those who helped us in difficult times. However, in expressing the truth of human nature and reflecting on the cruelty of war, redemption has different power in artistic appeal. But at present, the Japanese right-wing forces are still denying the Nanjing Massacre, and many people in the world know nothing about it. It is very difficult to film the Nanjing Massacre from the perspective of redemption. It takes time to wash away the sins slowly and wait for the awakening of the sleeping conscience.
