Step onto Beixiangdao Road where Tang Dynasty ghosts whisper through sycamore leaves! This hidden alleyway near Xi'an's east gate bursts with unexcavated artifacts underfoot - spot pottery shards stamped with 8th-century seals beside murals of Silk Road caravans. The real magic hits at twilight when local musicians play "Three Variations of Yang Pass" on ancient Xun flutes. Pro tip: Grab piping-hot 'Jing Gao' rice cakes from grannies' stalls, their osmanthus-glazed fragrance will transport you straight to a Zhang Xiaojing detective drama scene!
