During the birth and development of China historical documentary, a large number of outstanding works of art have been produced, such as Looking at the Great Wall, The Story of the Yangtze River, The Silk Road, The Forbidden City and Dunhuang. And the creation of these works also constantly promotes the development of China historical documentary. But everything will encounter its own "bottleneck period" in the process of development, and it is impossible to create and grow in depth. As far as the bottleneck of the development of historical documentary is concerned, the author thinks that it can be solved and broken through the following different expressions, so as to achieve prosperity and stability in re-creation.

First, people cooperate with each other to interview and explain.

Interviewing the parties, insiders or authoritative researchers of historical events and telling or commenting on historical facts through their mouths can enhance authority and credibility. The parties and insiders are not only witnesses of historical events, but their voices, smiles, gestures and actions all reflect their subjective feelings and thoughts and feelings about the expressed historical facts. In addition, the effective coordination of commentary can make the audience's cognition of historical facts more direct, vivid and concrete. In the documentary "Young Children", the whole film is more vivid by interviewing the descendants of young children studying in the United States and the descendants of American families staying with young children, supplemented by interviews with historical researchers.

Second, choose historical documents.

Historical documents refer to' historical images and historical texts' photographed and preserved at the scene of historical events or activities of historical figures, and are the life source and main carrier of historical documentaries. In the documentary "Children" series, by showing children's transcripts, photos, letters and other documents, it plays a vital role in creating a historical atmosphere, describing the historical process, showing historical details, and enhancing its historical facts and literature value.

Third, choose historical sites.

Historical sites refer to places where historical events occurred or places where historical figures lived, as well as their remains and relics. Some wonderful passages not only bring historical knowledge and information to the audience, but also bring beautiful artistic enjoyment to the audience for people to enjoy for a long time. In the documentary "Yuanmingyuan", by shooting the existing ruins to show all kinds of evil deeds of burning Yuanmingyuan when Eight-Nation Alliance invaded China, it can arouse the patriotic enthusiasm of the audience, awaken national consciousness and arouse emotions.

Fourthly, simulate image reproduction.

There are four main forms of this expression: finding professional actors to play historical figures, selecting film and television dramas, using high technology to restore historical scenes, and using subjective lenses. In the documentary "Dunhuang", the contents of flying Dunhuang murals are vividly presented to the audience through the actors' acting skills, bringing the audience beautiful enjoyment. In Yuanmingyuan, by intercepting the fragment of the film The Last Emperor, what Lang Shining, a court painter, saw and heard in that year was displayed more intuitively. Using modern computer stunts to truly restore the grand occasion before the destruction of Yuanmingyuan, the audience could not help but be impressed by the superb architectural art at that time, and even more shocked by the dazzling treasures inside; In "Children", the subjective lens is used to simulate the perspective of children in that year, and the scene they studied at that time is reproduced, which is more realistic.

Fifth, the alternate appearance of real time and space and historical time and space.

Real time and space generally shows the activities of the film crew in the process of searching and shooting, such as the investigation and exploration of related relics, sites and sites, and interviews with parties and insiders. Historical time and space are mainly created by interview content, pictures of historical relics, pictures of historical documents, simulated reproduction pictures and commentaries. Dunhuang talks about flying murals, the real time and space is an interview with historians, and the historical time and space is the scene where actors perform flying murals. The two cooperate with each other and complement each other, and * * * completes the wonderful presentation of this content.

Sixth, detail treatment enhances the appeal of the work.

In historical documentaries, details are the main externalized way to deeply show the complex psychological activities of characters. Through the details, the audience can not only better understand the inner world of the characters and enrich the overall image of the characters, but also better touch the details of historical figures and events and feel the fresh historical pulse. In Dunhuang, through the detailed display of a grotto mural, a complete Dunhuang mural is presented to the audience from part to whole, which plays a good role in promoting and setting off the overall style.

Seven, enhance the visibility of story narrative.

Storytelling has been used since Flahadi's time. "The choice of the theme of documentary creation should put people or things with stories in the first place." Storytelling can enhance the suspense of the work, enhance the interest of the work and attract the audience to continue watching. The documentary "The Rise of a Great Power" is completed by telling the story of the rise of a great power, which not only attracts the interest of the audience, but also improves the popularity of the work.

To sum up, the origin of historical documentary is a realistic reflection of people and history, which has strong historical value. Moreover, the development of historical documentaries still has a long way to go, and it needs more discussion and summary, perfecting and supplementing new expression techniques in order to create more and better outstanding works.
