In late June, the 34th French International Sunshine Documentary Festival was held, and a batch of Chinese documentaries caught the attention of international peers. Documentaries are an important carrier for telling the story of China well and building bridges for communication and dialogue among different civilizations. In recent years, Chinese documentaries have continuously updated their creative concepts, with increasingly diverse subject types, diverse aesthetic styles, and increasingly diverse cooperation models between China and foreign countries, achieving various results. In terms of enhancing narrative ability and showcasing the effectiveness of international communication, natural documentaries are one of the most popular types of documentaries. Compared to documentaries on other themes, natural documentaries are more likely to cross the barriers of language and culture, and have a wider range of dissemination. At the same time, this type of work is time-consuming, requires high investment, and has high technical requirements. British nature documentaries represented by The Blue Planet, Frozen Planet, etc., and French documentary films represented by Migrating Birds, The Diary of Emperor Penguins, etc. have created many ratings records. In recent years, Chinese documentary filmmakers have made unremitting efforts and meticulously crafted a series of natural themed documentaries that have caught the attention of international peers, such as "National Parks: Wildlife Kingdom", "Wild Four Seasons: Rare Wild Animals in China", "Snow Leopard and Her Friends", "Heron World", "Nest in Nest Out", etc., which have had a good response at home and abroad. Among them, "National Parks: Wildlife Kingdom" has been broadcasted in more than 100 countries and regions worldwide, reaching international excellent standards in narrative style, aesthetic presentation, and technical quality, making it one of the representative masterpieces of contemporary Chinese nature documentaries. Chinese path to modernization attaches importance to the harmonious coexistence of man and nature. These nature documentaries not only tell the world the stories of giant pandas, Snub-nosed monkey, Siberian tiger, snow leopards, Tibetan antelopes and other rare animals, but also reflect the value concept of building a community of human and natural life, and spread the oriental wisdom of Unity of Heaven and humanity. After watching National Park: Wildlife Kingdom, American film critic John Edward Bettencourt sighed: "China has made great efforts to improve environmental quality and protect biodiversity." In the documentary "Elephant North Along the Road", which won the "International Communication Power Award of Chinese Culture" at the 2021 China US Film Festival, more than 10 charmingly naive elephants fascinated audiences at home and abroad, The staff and civilians who silently protected them along the way have even moved many people. This is precisely the value of nature documentaries - facing the increasingly severe ecological environment, humans should work together to address challenges, actively share experiences, and make environmental protection deeply rooted in people's hearts. Humanities documentaries have traditional advantages in Chinese documentaries. The long history and profound cultural traditions provide core resources for civilization dialogue, while models such as Sino foreign joint filming and production inject multidimensional perspectives into the film, enhancing its international influence. For example, 'Confucius' presents the long-standing Confucian culture and its modern inheritance, and has launched an international version of the Chinese English collaboration for overseas dissemination; The co production of "The Great Poet Du Fu" by China and Britain interprets Du Fu from an international perspective and seeks his spiritual relics in contemporary China; The Sino British co produced 'Treasures of China' seeks Chinese cultural genes in museums and presents the legendary story of Chinese cultural relics through over 20 rare treasures; Hundred episodes
