We just learned about the Houmuwu Ding.
Another part of ancient Chinese art is the Six Ritual Jades.
Long ago in China there were six jade things that important people like kings or emperors would keep to show that they were powerful and important.
The first of these was called a "Bi", which was a round disc with patterns on it and a hole in the middle.
Some people believe that the six ritual jade things each had a different meaning, and "Bi" was for heaven or sky.
