Chinese guardian lions, or imperial guardian lions, are a traditional Chinese architectural ornament, but the origins lie deep in much older Indian Buddhist traditions. Typically made of stone, they are also known as stone lions or shishi (). They are known in colloquial English as lion dogs or foo dogs / fu dogs.
