When deciding to design the blue and white theme suit, Daryou's designers were thinking about the name of the product. First of all, I must think of "blue and white porcelain". If I use this, I will not rule out that Jay Chou has accused us of infringement. Secondly, the names of blue kite, green kite, misty rain green, etc. all appeared in the designer's mind one by one and were rejected one by one. Until the designer saw an introduction written on a piece of porcelain introducing Ming Dynasty blue and white porcelain in Jingdezhen. Suddenly he was severely caught by the word "underglaze. Therefore, this set of products is named "underglaze green"
