The Altar of the God of Agriculture, located on the western side of the axis' southern section, is a microcosm of the city's efforts to preserve this heritage. The axis also contains Qianmen, which has remained a bustling commercial district since the Qing Dynasty (1644-1911) and retains much of the old-time charm of its hutong (traditional alleyways), which draw visitors from around the world.

The layouts of the axis' streets and lanes have been preserved while residents' amenities have been upgraded. And several ancient guild halls and residences of historical figures have been opened to the public after renovations.

Qianmen's 200-year-old Tianleyuan Theater offers Peking Opera experiences with modern elements.

Stage art and lighting have been introduced while screens showing Chinese and English subtitles make the performances accessible to diverse audiences. The performances have also introduced immersive and interactive elements, such as enabling patrons to don opera costumes and other experiences that appeal to younger guests. Tianleyuan's visitor numbers returned to pre-pandemic levels this summer.

A growing number of Beijingers are expressing support for the World Heritage nomination, says a report on the axis published in April.

"More people are exploring these sites, tapping into the city's past and recognizing its identity," says Beijing Institute of Surveying and Mapping expert Chen Pinxiang, who creates 3D models of destinations along the axis.
