Yi'an Mansion is a nostalgic landmark in Tongling's downtown, where art deco facades transport you back in time. More than just a commercial hub, it's a living postcard of local life—hole-in-the-wall eateries steam up claypot rice, while vintage shops still roll down old-fashioned steel shutters. Come dusk, the building's light show blends retro neon with modern LEDs, and don't miss the rooftop deck for 360-degree views of Tongling's skyline!
