"The Hidden Secret of the Great Wall of China Finally Revealed"

In a study, it was revealed that the previous archaeological theory stating that some parts of the Great Wall of China have undergone modification or repair over a considerable period of time after its construction.

"Alang-alang"

The organic material used in the construction of segments and watchtowers of the Great Wall of China carries more environmental and scientific information than previously known. Researchers, whose findings were published in the journal Nature, conducted an analysis of the chemical composition of reeds collected from ancient parts of the Great Wall located in Gansu and Xinjiang. In this study, the researchers used a combination of chromatography techniques and isotopic analysis.

The implementation of this technique is a first example of the method used in analyzing archaeological data originating from the Great Wall of China.

Kromatografi is a method used to separate materials into their components by dissolving them in a solvent and flowing them through a specific system that is capable of capturing and separating each component.

This system can vary depending on the experiments conducted, but one of the most commonly used chromatography systems is the color indicator paper that produces horizontal lines on the Covid-19 antigen test.

"Climate Change"

Scientists utilize preserved materials to study local history. For example, research shows climate change after the Song Dynasty (1160 AD).

"Natural Modification"

This research provides support for the archaeological theory that speculates that some of the walls have undergone modification or improvement over a long period of time after the construction process.

Some of the most famous parts of the Great Wall of China were built during the Ming Dynasty in the 15th century. It is made of bricks and stones. However, this is only a segment of a network that spans across northern China and uses various construction materials.

Dibangun sejak tahun 475 SM, sebagian menggunakan bahan lokal seperti alang-alang, kayu, dan tanah berkerikil.

Built since 475 BC, partly using local materials such as thatch, wood, and gravel.

"A series of attractive forts and earth fortresses were built after the unification of China in 221 BC."

According to the researchers, as quoted by The Jerusalem Post website.

The translation of the word "Pertahanan" from Bahasa to English is "Defense".

The researchers state that the initial purpose of the Great Wall of China was to protect the Xiongnu and Xianbei states in the north. This defense was vital in the 2nd century BC to expand the territory of the Han Dynasty to the western border, including the Xinjiang and Gansu provinces, which have become the focus of research. This paper highlights the potential of such material as a valuable biogeochemical archive for the study of ecosystems and hydrology that have been altered by humans.

Therefore, through the analysis of these ancient plants, the scientific community can delve deeper into the environmental conditions at specific points in history along the Great Wall of China.
