@infinitewhylab: WHY were the Longyou caves carved with such precision? Deep beneath Zhejiang, China, massive underground chambers were carved directly into solid rock… covering thousands of square meters with remarkable consistency. No historical records describe their construction. No tools were found inside. Yet the walls show repeated chisel patterns… as if the same method was used across the entire complex. So why were these chambers built… and why was nothing written about them? — Sources: Wikimedia Commons (CC BY-SA) #History #ancienthistory #archaeology #ancientengineering #longyoucaves #historyfacts #mystery #LearnOnTikTok #infinitewhylab
