Introduction to the exquisite cultural relics of Yandu: The artifacts unearthed in Yandu are mostly decorated with animal images such as tigers, leopards, and oxen, exuding the unique local artistic style, which is very different from the artifacts unearthed in the Central Plains region. The Bo Ju Ge, a bronze vessel from the Yan Kingdom of the Western Zhou Dynasty unearthed from Liuli River in Beijing, is decorated with cow-face patterns on the vessel's body, feet, lid and lid buttons.
