A set of chime bells unearthed from an ancient tomb in north China's Shanxi Province could still ring out the right note.
With a history of 2,500 years, the chime bells were excavated from a tomb dating back to the Zhou Dynasty (1046-256 BC).
After restoration, researchers chose six chime bells to perform the renowned Chinese folk song "Jasmine," a piece of music that was included in Giacomo Puccini's opera Turandot.
To protect the relics, researchers used specially make bell sticks to ring the bell.
