“A defensive tower” I say looking at \u77f3\u6d1e3\u53f7\u654c\u53f0. What stories lie within these stones? Today we explore \u77f3\u6d1e3\u53f7\u654c\u53f0 a defensive tower. It stands as a silent witness to centuries of Chinese history.
The Great Wall is one of the largest construction projects ever undertaken. It is a testament to China’s enduring strength. The wall includes numerous walls built over two millennia. These walls stretch across northern China and southern Mongolia. The most extensive portion dates back to the Ming Dynasty. That was between 1368 and 1644. It runs for approximately 5,500 miles. That is 8,850 kilometers. It goes from Mount Hu near Dandong to Jiayu Pass west of Jiuquan.
\u77f3\u6d1e3\u53f7\u654c\u53f0 is part of this immense structure. The wall traces the crestlines of hills and mountains. About one-fourth of its length consists of natural barriers. These are rivers and mountain ridges. Around 70 percent is constructed wall. The rest is ditches or moats. The Great Wall was designated a UNESCO World Heritage site in 1987.
Construction of the Great Wall began centuries before the Ming Dynasty. Large parts of the fortification system date from the 7th to the 4th century BCE. In the 3rd century BCE, Shihuangdi connected existing walls into a single system. He was the first emperor of a united China. This was under the Qin Dynasty. The wall’s eastern terminus was traditionally considered Shanhai Pass. That is in eastern Hebei province. The wall extends for about 4,160 miles. That is 6,700 kilometers. Government investigations in the 1990s revealed more sections. Aerial and satellite surveillance confirmed that the wall stretched continuously. The total length of the Ming wall was announced in 2009.
The Great Wall developed from disparate border fortifications. Individual Chinese kingdoms built castles. They sought protection from neighbors and barbarian invasions. The state of Chu began constructing a permanent defensive system around the 7th century BCE. Other states followed suit. The Qi state created a perimeter wall using river dikes and bulwarks. The Zhongshan state built a wall to thwart invasions.
In 221 BCE, Shihuangdi unified China. He ordered the removal of fortifications between states. He sent Gen. Meng Tian to garrison the northern border. His task was to link existing wall segments into the “10,000-Li Long Wall.” Construction began around 214 BCE. It lasted a decade. Hundreds of thousands labored on the project. After Shihuangdi’s death, the wall fell into disrepair.
The Great Wall never effectively prevented invaders. However, it became a symbol of Chinese civilization’s strength. During the Ming Dynasty, construction of the most extensive section began around 1474. Ming rulers adopted a defensive strategy. They reformed and extended the Great Wall.
The Ming wall extended from the Yalu River to the Taolai River. It wound its way through several provinces. Strategic passes and gates were placed along the wall. These passes were heavily garrisoned. They were vital to the defense of the capital.
Today \u77f3\u6d1e3\u53f7\u654c\u53f0 stands as a reminder of China’s past. It reflects centuries of construction and defense. It embodies the enduring spirit of Chinese civilization.
