In the 11th century BC, Yan's capital was based in what is now Liulihe Township, Fangshan District, Beijing, where a large walled settlement and over 200 tombs of nobility have been unearthed. Among the most significant artifacts from the Liulihe Site is a bronze ding with inscriptions that recount the journey of the eldest son of the Duke of Yan, who delivered offerings to the King of Zhou in present-day Xi'an and was awarded a position in the king's court.
