Scholars today agree that porcelains bearing Qingyitang and Caihuatang hall marks were first produced in the Qianlong reign and over several subsequent generations, in a wide variety of forms and decorations. Therefore, dating of these porcelains shall rely on the characteristics of their forms and decorations. The present examples, based on the style of 'Immortals' decoration and underglaze-painting technique, may be attributed as Qianlong/Jiaqing period.pare, for a later example, the Daoguang-marked bowl of the same "Immortals" design in underglaze-blue and puce-enamel decoration in this sale, lot 169.

Wilson further suggests that since the same design appears on both Yanghetang- and Qingyitang- marked vessels, it is possible that the Qingyitang zhi hall mark also has an imperial connection. For a closely related example, see Christie's London, 15 June 1998, lot 169 (pair of Qingyitang zhi -marked bowls). Qing dynasty scholar Xu Zhiheng (1877-1935) noted in Yinliu zhai shuoci that porcelains bearing Caihuatang zhi hall mark are imperial wares made in the Qianlong period, but other scholars have sugges
