CGTN's Ioana Gomoi takes you to Beijing's Drum and Bell Towers – a duo of landmarks standing at the northern end of the city’s historic Central Axis. For more than 600 years, their bells and drums helped mark the rhythm of daily life. Even the 25 drums reflect the 24 solar terms of the traditional Chinese calendar. Today, they remain a powerful reminder of a Beijing where time was once heard, rather than seen.
