Compare this set of four paintings with those from an album, probably by the same painter, dated Kangxi in the C.T.Loo collection, Paris, illustrated in Michel Beurdeley (et al.)'s Chinese Erotic Art, Secaucus, N.J.: Chartwell, 1969, pp. 74, 75, 76, 96, 103, 113, 114, 116 (all col. pla.).
Free translations of the two couplets appended to the paintings are given below:

'On the Embroidered Couch'
Around the stove the burning candles reflect her rouge make-up;
The plum blossoms in the paper screen are unusually fragrant.
Among the sable and gem bed clothes their amorous links are redoubled; Frosty flowers in profusion reach the bed of coupled pleasure.

'Fondling the Strings of the Lute'
First I tried a fragrant bath, made myself clean;
On account of my infatuation with decoration and beauty I begin to lose control.
When we meet, without a word we are in each other's arms;
How many deep, deep affections I shall entrust to this beauty!
