The Great Wall of China, an architectural marvel, spans roughly 13,170 miles and was built for defense against invasions while also serving as a cultural symbol. Its construction involved various materials and labor forces over several dynasties, highlighting its historical significance and monumental scale. When compared to Qin Shihuangdi's tomb and the Terracotta Warriors, the Great Wall stands as a greater testament to his legacy as it reflects the enduring impact of ancient Chinese civilization.
