How Long Is the Great Wall of China, Really?
The Great Wall, a symbol of the Chinese nation, has long been admired by the world for its magnificent scenery and long history. But have you ever wondered just how long this giant dragon truly is?
Many people say that the Great Wall is 8,851 kilometers long, which is where the name "Wan Li Chang Cheng" (literally meaning "Ten Thousand Li Long Wall") originates. However, the actual length of the Great Wall is far greater than that. According to statistics, the total length of the Great Wall built in different historical periods, including overlapping sections, is approximately 21,196 kilometers (13,171 miles). This figure is even longer than the radius of the Earth!
To better understand this number, let's delve deeper into the following aspects:
1. Calculation Methods for the Great Wall's Length:
- Inclusion of All Historical Periods: The length of 21,196 kilometers does not refer to the length of the wall built during a single dynasty. Instead, it encompasses all sections built from the Warring States Period to the Ming Dynasty, including those that have disappeared or remain as ruins.
- Counting Overlapping Sections: Due to historical reasons, sections of the Great Wall built in different dynasties may overlap. These overlapping parts are also included in the total length calculation.
- Utilization of Modern Technology: In recent years, archaeologists and surveyors have employed advanced technologies like satellite remote sensing and GPS positioning for more precise measurements of the Great Wall, leading to more accurate length data.
2. Factors Influencing the Great Wall's Length:
- Dynastic Changes: The emphasis on border defense and the strategies employed varied across different dynasties, resulting in differences in the scale and length of the Great Wall constructed during their respective reigns.
- Geographical Environment: The geographical environment where the Great Wall stands is complex and diverse. To adapt to different terrains, its direction and length also vary.
- War and Peace: During times of war, rulers often reinforced and extended the Great Wall to resist invasions. In contrast, maintenance and repair might be less of a priority during peaceful periods.
3. The Significance of the Great Wall:
The Great Wall is not only a remarkable feat of military defense engineering but also a historical monument embodying the wisdom and sweat of the Chinese nation. It has borne witness to the rise and fall of Chinese civilization and carries profound cultural connotations.
In conclusion, the length of the Great Wall is a complex and ever-changing concept. 21,196 kilometers is simply a relatively accurate figure. However, regardless of its precise length, the Great Wall's historical value and cultural significance as a spiritual symbol of the Chinese nation will endure forever.
