Along the Beijing Central Axis, pedestrians can hear the dang-dang sightseeing bus passing by, so named for the copper bell that rings to announce its presence. The cultural mainstay has become more prominent since the area was added to the UNESCO World Heritage Site list in July.

Red lanterns sway gently before the windows within the quaint confines of the dang-dang bus. Intricate ancient motifs and tile designs adorn the roof, evoking a nostalgic sense of old Beijing. Above them, images of the Beijing Central Axis' renowned landmarks unfurl a visual narrative of the city's history.

Beside the seats, tables are elegantly laid with an array of culinary delights. Passengers indulge in panoramic views of the Central Axis while sampling the flavors of authentic Beijing snacks.

"The Great Beauty Central Axis Sightseeing Bus features a novel iteration of the classic dang-dang bus," shared Yun Haibing, the director of the Beijing Tourism Distribution Center's market management department.
