30° North Latitude, an umbilical cord of civilization that stretches across the land of China

At the waist of the earth, 30° north latitude is like an intangible link of civilization, which runs horizontally through the vast territory of China.

This line, called the "magic latitude" and thus called by geographers, winds for about 5,000 kilometers in China. It connects glaciers, which belong to the Qinghai-Tibet Plateau, and connects red soil, which is in the Sichuan Basin. It connects fertile fields, which are in the Jianghan Plain, and it connects water towns, which are in the Yangtze River Delta.

In the early summer of 2025, there was a documentary called "Listening to China Along the Latitude". It used a listening attitude to interrogate the historical memory along this latitude, making those silent landmarks make their voices heard again.

When the original sound of the scene sounded in the screening room, the participants seemed to hear the heartbeat of the earth. That heartbeat is the pulse of Chinese civilization that has never been cut off for five thousand years. This is the situation.

The love of the mountain: the thousand-year contract between the guardian and the white-lipped deer

Deep in the folds of the Hengduan Mountains , Genqiu "dialogues" with the white-lipped deer using whistles.

This call originating from Bon rituals has echoed in this land for thousands of years.

After arranging the infrared camera properly, the scene of him turning around to accompany his child was recorded by the documentary lens. These two scenes formed a montage, expressing the simplest inheritance of the people of Dashan, that is, guardianship is not only a contract with nature, but also the consciousness of engraving this awe into the blood of the next generation.

**Chu opera** artists have rough hands. These hands are not deliberately performing, but sliding on the **erhu** strings. Their singing is mixed with the sound of wind from **Jianghan Plain** and the fragrance of rice from **Jianghan Plain**.

As experts say, this is not only a slicer of the history of opera, but also a vivid example of how Chinese culture has moved towards "beauty for all" in "each has its own beauty".

"Listening to China Along the Latitudes" is unique in that it uses "listening" to reconstruct the audio-visual language.

Obsessing with the reality of this sound allows the humanistic memory hidden in the urban texture to be more prominently displayed.

The urban soundscape composed of these sounds has a more historical texture than any commentary.

After ten months of creation, five episodes were formed. What "Listening to China Along the Latitude" finally presents is not only the unique geographical landscape of 30° north latitude, but also a spiritual map of contemporary China.

Spanning from the area called the "Qinghai-Tibet Plateau" to the area called the "East China Sea Coast", on this specific latitude, there are mysterious bronze objects that originated from "Sanxingdui"; at the same time, there is also the civilization carried and represented by the jade cong called "Liangzhu". Here there are both the "jiangtan" where the poet "Qu Yuan" once recited poems and walked around, and the "water town" described by the writer "Lu Xun".

According to experts from Tsinghua University, this cultural concept of "harmony without difference" is precisely the code for the fact that Chinese civilization has not broken down after five thousand years.

When geographical latitude meets art with visual and auditory effects, a different way of telling the story of China emerges. It is not like an academic paper that covers vastness and depth, but instead leans down and listens to the warm atmosphere of humanity contained in the beating pulse of the earth.

By July 2025, this documentary will be broadcast on the CCTV screen. The Chinese treasures existing at 30° North Latitude will use sound to awaken the cultural memory in the hearts of every viewer.
