His rubbing of the Boju Ge, which is regarded as one of Jia's representative works, was given to former French president Jacques Chirac as a present by China in 2011.
Boju Ge is an ancient three-legged bronze vessel used for sacrifices that was unearthed in Beijing in 1974 that dates to the Western Zhou Dynasty (c.11th century-771 BC).
In recent years, Jia has also been devoted to the inheritance and promotion of whole-shape rubbing, including training younger generations to perform the almost-lost technique.
