The Drum and Bell Towers are must-visit sites in Beijing. Once responsible for the city's time-keeping, they are 600 years old and among the country's most iconic and best-preserved ancient architectures. The Drum and Bell Towers are geographically significant too as the starting point of the all-important central axis in the capital city. As part of Beijing's livestreaming marathon along the central axis, CGTN's Sun Ye and China Daily's Owen Thomas Fishwick take you into and all the way up in the Drum Tower.
