Li Shulei, a senior official of the Communist Party of China (CPC), said on Friday that a thorough study of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era is key to understanding contemporary China.
Li, a member of the Political Bureau of the CPC Central Committee and head of the Publicity Department of the CPC Central Committee, made the remarks when meeting in Beijing with foreign representatives attending an international symposium on Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.
Since the 18th CPC National Congress in 2012, the CPC Central Committee with Comrade Xi Jinping at its core has led China to achieve historic accomplishments, Li said, adding that the CPC is willing to enhance exchanges and mutual learning with political parties around the world on state governance.
The foreign participants noted that this visit has enabled them to witness China's progress in many areas, expressing their willingness to learn more about the thought and draw on wisdom and strength to boost national development.
Studying Xi Jinping thought key to understanding contemporary China, senior official says
A documentary has revealed how generations of fishermen in south China's Hainan Province navigated the South China Sea for centuries with no GPS, no weather forecasts, relying only on a handwritten manual known as the Genglubu.
The documentary, Genglubu: Charting the South China Sea, premiered Thursday on China Global Television Network (CGTN).
Unintelligible to outsiders, the Genglubu was an invaluable navigational guide for fishermen and one of the most important items they carried on board.
"What Tanmen fisherman do is dive into the sea and catch fish ourselves. Finding better reefs means catching more fish. And that's why we keep going back to the South China Sea. My grandfather and father would study it like homework before setting out," said Wang Zhendong, curator of the Genglubu Museum in Hainan's Qionghai City.
Wang cannot personally interpret the old manuscript, but he understands its importance: his father studied it before every voyage, and his grandfather trusted it with his life.
"When electronic equipment fails, if you don't understand navigation, how are you going to bring everyone home safely? A captain needs to understand experience. So where does that experience come from? It comes from the Genglubu. It's the ancient knowledge recorded generation after generation," said Wang Shubao, Wang Zhendong's father.
Over generations, that knowledge was written down in the Genglubu.
"Geng" referred to both time and distance traveled at sea. One "geng" was about two hours of sailing, or roughly 10 nautical miles.
"Lu" referred to compass bearings and direction, while "bu" meant "book."
Without modern instruments, fishermen learned to read the sea -- its currents, its depths, its changing moods.
Knowledge shaped their navigation. The Genglubu recorded that knowledge.
One line in it says: From Tanmen port to the Xisha Islands' Zhaoshu (Paracel's Tree Island), follow the direction of the Qian, Sun, which is northwestward. It covers a distance of some 150 nautical miles.
Just a few lines, enough to guide a boat across open water.
One surviving manuscript, copied by Wang Shitao, records 279 routes, making it one of the most detailed versions of the Genglubu known today. Its routes link Hainan with island groups across the South China Sea, with some extending even farther.
"Before Zheng He's voyages (1405-1433) to the Western Seas, the fishermen had already been working these waters of the South China Sea," said Zhou Weimin, a professor at Hainan University.
Experts say the Genglubu is more than a practical guide to navigation; it is also a record of China’s maritime history, cultural heritage and the accumulated wisdom of a people shaped by the sea.
"The Genglubu is a navigation handbook born of experience accumulated through long-term practice. It forms an integral part of China's maritime system. It is a cultural legacy created by our ancestors and a crystallization of the wisdom of a people with a long maritime tradition," said Liu Yijie, a professor at the Center for Studies of Fujian and Taiwan at Fujian Normal University.
