Although the Yongzheng period (1723-1735) was short-lived, the economy developed, the society was stable, and the porcelain-making technology advanced by leaps and bounds. According to the archives of the Office of the Qing Palace, Emperor Yongzheng himself repeatedly stipulated the shape and pattern of porcelain, which required not only the appropriate size of each part of the fired porcelain, but also the momentum and charm, and the rhythmic beauty of the outline lines. The imperial porcelain to be burned must be examined and approved by Emperor Yongzheng before it can be fired. According to the will, Nien Xiyao and Tang Ying, the pottery supervisors of Jingdezhen Imperial Kiln Factory, gathered the best porcelain craftsmen in the country, spared no expense and tried their best to burn it, so as to win the favor of the emperor and made unprecedented brilliant achievements. It should be said that the aesthetic taste of Emperor Yongzheng played a decisive role in the modeling and painting style of porcelain in this period. "
