From the text on the reverse side of the screen, we learn that it was meant to be offered to Mr Deng for his 70th birthday by Liao Chang-Ling, imperial supervisor and official in charge of the imperial cereal stores in Tong Zhou city. Mr Liao was also a colleague of Mr Deng's son. The screen was offered during the Spring of the 'Gengchen year' of Kangxi reign which corresponds to 1700.
Apart from these specific informations, the rest of the text is a formal praise to Mr Deng.
