Summary

TLDRThe Great Wall of China, a 13,000-mile-long serpentine structure, has a complex history dating back to the Chunqiu period. Initially built by feudal states for protection, it was expanded by Emperor Qin Shi Huang to defend against northern invasions. Forced labor was used extensively, leading to a notorious reputation. Despite its formidable presence, the wall was breached by Mongols in the 13th century. The Ming dynasty reinforced it with bricks and stones, but its purpose diminished with the Qing dynasty's expansion. Today, a UNESCO World Heritage Site, the wall stands as a cultural icon, attracting millions of tourists and undergoing preservation efforts.
