Lion introduction: In addition to porcelain and white marble carvings, the Porcelain House also has a set of cultural relics that cannot be ignored, that is, more than 300 lions of various sizes, which guard every corner of the Porcelain House according to their respective sizes. At the door outside the wall, there is a pair of stone lions from the Ming Dynasty, nearly one meter high, with exquisite workmanship and the slightest trace of hair on the temples. Pushing open the fence, walking through the courtyard paved with porcelain tiles, and stepping on the steps made of white marble, a dark green porcelain lion from the late Ming and early Qing dynasties stood at the door. It is said that a pair of these porcelain lions once stood guard in front of Duan Qirui's mansion. Now, the other one died in the flames of war, leaving only this one alone. There are figures of lions in every corner on the roof, either looking up to the sky and roaring, or bowing their heads in meditation, with different shapes. These stone lions span the Eastern Han, Tang, Song and Qing dynasties, and each one is extremely valuable.
