The ancient geographical masterpiece "Notes on water classics" records more than a thousand large and small rivers and related historical sites, people's palms, myths and legends. In today's scientific and technological development, the direction and source of rivers are not difficult, but they were difficult before the millennium. Taking the "Notes on the Water Classics" as an example, the author Li Daoyuan is a northerner, subject to various restrictions can not personally go to some remote areas to actually investigate, so the southern water system recorded in the book is relatively simple, and even some errors, the Tang Dynasty politician Du You pointed out the error in the source of the Yellow River in the "Water Commentary".
The world-famous rivers (Yellow River, Yangtze River, Lancang River) that nurtured the Chinese nation and the long history of civilization in the Indochina Peninsula all originate in the western part of our country, and the dispute over the birthplace of these three rivers has never stopped, which also shows that our Chinese nation is a nation with a strong desire for knowledge. Of the three famous rivers, the source of the Yangtze River is the most controversial.
About where is the source of the Yangtze River? Before the Ming Dynasty, a geography book of the Warring States Period 2,000 years ago, Yugong, was generally used: "Minshan Guide River, East is Tuo, and East is Li; Cross the Jiujiang River, as for Tanglin, East to North, Huiyu Hui; East is the Zhongjiang River, into the sea", Minshan refers to a folded mountain range in the southwest of Gansu Province that extends to the north of Sichuan Province. This river is the Yangtze River.
In the Ming Dynasty, Xu Xiake "northern calendar three Qin, Antarctic five ridges, west out of shimen Jinsha", and finally found out that the Jinsha River originated in the southern foothills of the Kunlun Mountains, more than a thousand miles longer than the Min River, so he concluded that the Jinsha River was the source of the Yangtze River. For a long time after this statement appeared in the world, no one approved or explored it, which was enough to see the hardships of finding the source of the Yangtze River.
In 1976, after the expedition team inspected, it was believed that the Tuotuo River was the source of the Yangtze River, in addition, the Dangqu and Chumar Rivers were also the source of the Yangtze River, and they were distinguished by orientation: the Tuotuo River (the Tuotuo River originates from the Jiang Gendiru Glacier in the Eastern Snow Mountain of Gradam, according to the principle of "only long and farther", saying that there is no problem in saying that the Gradan Dongxue Mountain or jiang gendiru Glacier is the source of the Yangtze River), the south source of the Dangqu, the north source of the Chumar River. 32 years later, in 2008, the national scientific expedition team of the Chinese Academy of Sciences used modern high-tech technologies such as global satellite positioning systems, geographic information systems, and remote sensing technology for the first time to explore the source of the Yangtze River. After measurement, it was concluded that the amount of water in Dangqu among the three major sources was larger and the longest length, which should be the source of the Yangtze River.
However, the above statement has not yet been filed and approved by the state, the world's most advanced surveying and mapping instruments, measured the length of the longest tributary of the Tuotuo River is 348.63 kilometers, Dangqu is 360.34 kilometers, 11.71 kilometers longer than the Tuotuo River. If this conclusion is recognized by the state, it means that the length of the Yangtze River will be renewed, and Chinese geography textbooks will be rewritten.
Since ancient times, people's search for the truth of things has never stopped, putting forward confusion, observation, exploration, and conclusions, and people continue to enrich themselves in the process. The change of seasons, the flight of the northern geese to the south, and the origin of the great rivers have been explored by the ancients, and we have also explored them today.
