Commonly known as "big fish plate", as there is usually a large carp painted inside the plate. This kind of fish pattern is mostly painted in blue and white, so it is often called "blue and white big fish plate". The moiré pattern on the plate is prominent, simple but bold, with a good composition. People from other places often call it "Shandong big fish plate" or "Boshan big fish plate", pointing out the place of origin.
