Did you know the Great Wall of China, encompassing all its branches and sections built over centuries, totals approximately 13,171 miles (21,196 kilometers) ? (Though the most famous and well-preserved section from the Ming Dynasty is about 5,500 miles long.)

Did you know building the Great Wall of China took over 2,000 years, from around the 7th century BC to the 17th century AD ?

Did you ever hear about the myth (and is largely exaggerated) of women convicts building the Great Wall with rice paste ? (Sticky rice was mixed with slaked lime to create an incredibly strong, waterproof mortar for sections of the wall, particularly during the Ming Dynasty, adding durability.)

Did you know the exact number of deaths building the Great Wall is unknown, but estimates range widely, with many sources suggesting hundreds of thousands, possibly over a million, workers died from harsh conditions, starvation, and exhaustion over centuries, earning it the nickname "the longest cemetery on Earth" ? (During the Qin Dynasty's initial massive construction, figures suggest up to 400,000 deaths, with many buried within the wall itself.)

Did you ever visit the Great Wall in person or would like to ?
