Step into Zhangwang Hutong and time-travel to old Beijing! This century-old alley hides courtyard homes with gray bricks beside vendors steaming douzhi (fermented bean drink). At dusk, elderly men play chess under pagoda trees—a living postcard of local life. Trace your fingers along walls bearing fading Cultural Revolution slogans, those poignant time capsules whispering stories of the city's resilience.
