Chief producer Liu Wen told reporters that even with today's technical conditions, it is not easy to shoot The Source of the Yangtze River. The source of the Yangtze River is 5800 meters above sea level, which is impossible for ordinary air helicopters to reach. Finally, with the support of the army, the film crew took a military high-altitude helicopter for the first time to overlook the real source of the Yangtze River from the air. "It is a huge glacier consisting of 76 glaciers, with a total area equivalent to Shanghai. This is a huge solid reservoir. The argument that the Yangtze River may be dried up is self-defeating in front of this group of pictures. Therefore, the first episode of "Let's Talk about the Yangtze River" was named' Endless Yangtze River'. " Liu Wen said.
Twenty years later, the Yangtze River represents the changes in China. In "Let's Talk about the Yangtze River", there are many scenes of "The Story of the Yangtze River", and many characters in that year's film also entered the new film again. Liu Wen said, "Let's Talk about the Yangtze River" was designed with a clear original intention, that is, to reflect the great changes brought by China's economic construction in the past 20 years with the changes of scenery, landforms and customs along the Yangtze River. Twenty years ago, The Story of the Yangtze River was a landscape film and an essay review, which made ordinary people who had never left their homes see the living conditions of people all over the motherland. In the past 20 years, many places along the Yangtze River have become tourist attractions, and they are no longer mysterious. So this time, we are people-oriented, telling stories in a purely documentary way, and showing the changes of the Yangtze River and China through comparison. However, it is more important for the audience to see that the change is actually the same. The fundamental reason for the great changes in the past 20 years lies in the consanguinity of Chinese culture. "
The audience's familiarity with The Story of the Yangtze River and their expectations for Let's Talk about the Yangtze River are a great pressure on the creators. "Now you can see foreign-made documentaries such as National Geographic Channel and DISCOVERY on TV, so our production concept should also be synchronized with the international level." Liu Wen said, "To this end, we used a lot of computer animation technology in the film to produce a three-dimensional fine vein map of the Yangtze River, with its main branches, tributaries and flow directions clear at a glance; In addition, when introducing some knowledge of historical relics, we also reproduced the historical events at that time in a realistic way.
