【正确答案】Pure and elegant beauty is the goal that porcelain pursues, and this ideal is best explained in the Blue and White Porcelain. As a typical artifact of Chinese porcelain, Blue and White Porcelain displays a white and blue world of conciseness and elegance, serenity and purity. Blue and White Porcelain is the most representative of Chinese porcelain. Among the porcelain exported during the Ming and Qing dynasties, 80 percent was Blue and White Porcelain. Blue and White Porcelain emerged long before the Tang dynasty, but it was not until the Yuan dynasty that this type of porcelain came to be produced in quantity, with the attendant masterpieces. The Ming dynasty witnessed the maturity of the art, and a large number of valuable pieces were produced in this period. Blue and White Porcelain occupies a prominent position in the Chinese porcelain industry, for it accords well with the culture and aesthetic spirit the Chinese have long pursued—simplicity, unaffectedness, and ease.
