Stroll down Ping'an Road in Nanjing where history whispers through every cobblestone. Well-preserved Republic-era buildings line this nostalgic street, their ornate facades contrasting with the lively hum of local life. Follow the aroma of duck blood vermicelli soup to hidden eateries, or sip Rain Flower tea in a 30-year-old teahouse - the owner's stories about old Nanjing make the perfect accompaniment.
