 Ratification was exchanged in Hong Kong on 26 June 1843.Pottinger wrote in a letter to the Earl of Aberdeen the following year that at a feast with Qiying celebrating the ratification, Qiying insisted they ceremonially exchange miniature portraits of each member of each other's families.Upon receiving a miniature portrait of Pottinger's wife, Pottinger wrote that Qiying "placed [the miniature] on his head—which I am told is the highest token of respect and friendship—filled a glass of wine, held the picture in front of his face, muttered some words in a low voice, drank the wine, again placed the picture on his head and then sat down" to complete the ceremony of long-term amity between the two families and the two peoples.
