The skyscraper-filled Beijing CBD gazes from afar at Dingdu Peak, once admired by Emperor Yongle of the Ming Dynasty. Chang’an Avenue connects the two, building a dialogue across time and space between the modern and the historic. The ancient Great Wall winds through the landscape, its weathered stones bathed in starlight, recounting the rise and fall of dynasties. At the pinnacle of Beijing, Dongling Mountain lies serenely under the Milky Way, having witnessed countless transformations of the earth. The comet C/2023 A3 (Tsuchinshan-ATLAS), with its multi-millennial orbital period, sweeps across Beijing carrying the ancient light of the stars, witnessing all the changes in the world.
