Imagine uncovering secrets hidden for centuries! A team from Tianjin University has used cutting-edge drone technology to discover over 200 hidden doors and gateways in China’s Ming Great Wall. One of these is a special “tumen,” a type of secret door designed thousands of years ago by the ancient philosopher Mozi during the Spring and Autumn Period.
The Great Wall, already known for its impressive length and history, just got even more fascinating. These hidden entrances were concealed so well that they remained unknown for generations. The discovery sheds new light on ancient Chinese engineering and military strategy.
Using drones allowed the team to explore parts of the wall that are difficult to access by foot. The aerial perspective provided detailed images and data, revealing the locations of these secret doors without damaging the historical site.
This finding doesn’t just add to the mysterious allure of the Great Wall but also opens up new possibilities for historians and archaeologists to understand how ancient civilizations protected and utilized such massive structures. Who knows what other secrets are waiting to be discovered?
