八公山
A scenic mountain area on the outskirts of Huainan, historically significant as the site where Han dynasty prince Liu An (179–122 BC) conducted Taoist alchemical experiments that led to the invention of tofu. The mountain is dotted with ancient temples, stone inscriptions, and Han-era cultural relics. It is also the site of the famous Battle of Fei River (383 AD), a pivotal moment in Chinese history.
