The YouTube video “This Great Wall of China Conspiracy Theory is Disturbing” by the channel “Bright Insight” explores the possibility that the Great Wall of China was built to keep Chinese citizens inside their country rather than outsiders out. The YouTuber argues that the presence of arrow slits facing inward on portions of the wall and the ability to climb over the wall from the outside in suggests that the wall was intended to prevent people from leaving China, rather than preventing people from entering. He also mentions that a significant amount of the wall remains hidden or buried, and that little information or imagery is available to the public on the remote sections. Additionally, he compares the Great Wall to other ancient structures like the pyramids of Giza and Göbekli Tepe, which he claims are shrouded in mystery and have been subject to suspicious archaeological practices.
