2. When selecting porcelain with gold or silver decorations, it is also necessary to wipe them with your hands to see if the decorative patterns are beautiful, elegant, and harmonious.

3. When selecting a complete set of ceramic products, it is important to check whether the glaze color, image, gloss, and style of each piece are consistent, symmetrical, and coordinated.

Plate and dish products have patterns on the parts where food is stored. For caution, it is advisable to choose products with fewer patterns on the edges or white blanks without patterns.
