Produce a scholarly annotated diagram explaining Jingdezhen blue-and-white porcelain, laid out like a page from a fine museum reference volume. Center a beautifully rendered porcelain vessel with cobalt-blue underglaze painting on luminous white glaze, and surround it with neat lead lines pointing to its structural parts from mouth rim and neck to shoulder, belly, and foot ring. Add supporting panels that unpack the craft: close-up swatches of classic motifs such as intertwined lotus scrolls, dragons among clouds, and misty landscape scenes; a short step sequence of the making process from kaolin clay shaping and cobalt painting to glazing and high-temperature kiln firing; and brief notes on glaze depth and pigment gradation. Write all annotations in clear, well-formed Simplified Chinese with tidy typographic hierarchy, free of typos or garbled strokes, set over a soft off-white paper texture with restrained ink-line borders. If the user request names a specific vessel shape, motif, era emphasis, or focus, adapt the diagram accordingly while keeping the same layout logic. Keep the mood refined, academic, and collectible; avoid cartoon styling, watermarks, and logos. User request: a plum vase with dragon motifs, emphasize the kiln-firing steps
