Adhering to the shooting concept that each episode is both Hainan and China, and at the same time is the only one, the film's main creators took three years to go deep into the hinterland of Hainan, digging out the unique elements that constitute Hainan's endowment, using local perspective, character story structure, documentary style expression, high-definition dual camera shooting, underwater photography, aerial photography and other comprehensive means, from ecology, food In terms of scenery, nationality, folk customs, urban civilization and marine spirit, it tells of a poetic and magical Hainan. Hainan has a relatively unique natural endowment and a relatively independent cultural evolution path. With its thousands of years of humanistic creation, it has participated in the construction of Chinese civilization and is an indispensable part of Chinese history and culture. However, in the historical records centering on agricultural civilization, Hainan, which is located in the remote area, has received little attention. Yang Xiaomin, the chief planner and writer of the film, believes that the biggest difference between the seven part humanities documentary "South of the Sea" and the past documentaries reflecting regional culture is that it goes deep into the interior of a regional civilization, and presents the internal power and mechanism of the growth of a civilization from the changes in nature, history and the fate of characters. The value of the film lies in, It not only reconstructs the cultural territory of Hainan with images, but also illuminates the long hidden history of Hainan with the rational spirit of the 21st century.
