Step into Keyuan Garden and be transported to Qing Dynasty Beijing! This hidden courtyard residence, once home to scholar Yu Yinlin, perfectly preserves traditional northern Chinese architecture. Wander through blue-brick courtyards under intricately carved gate towers, where hanging flower doors and zigzag corridors whisper tales of scholarly elegance. Don't miss the 200-year-old jujube tree that still bears fruit! Visit at sunrise when golden light filters through ancient branches onto stone pathways - the perfect moment to capture the aesthetic life of old Beijing's literati.
