Why is the Great Wall of China considered a national symbol in China?

The Great Wall of China is considered a national symbol because it has been deeply integrated into Chinese mythology and popular symbolism for centuries. By the 20th century, it became widely regarded as a definitive national icon.1

Historically, the wall represented the traditional division between Chinese civilization and the lands to the north, as evidenced by inscriptions such as "First Pass Under Heaven" found at the Shanhai Pass. Beyond its symbolic status, the structure is recognized as one of the most remarkable engineering feats in history, having been built and reinforced over two millennia by various dynasties to protect the Chinese frontier and control trade. Its cultural significance is further underscored by its designation as a UNESCO World Heritage site and its status as one of the New Seven Wonders of the World.1234
