In Chinese mythology, peaches are a symbol of immortality.
Fable: an emperor who fell in love with a male courtesan who picked a particularly sweet peach and takes only one bite of it. He gave the rest of the sweet peach to the emperor. The emperor was so enamored by the gesture that he publicly declared his love for him.
Ever since, the love between two men has been referred to as ‘the sharing of the peach’ in ancient Chinese culture among others.
The Love Song of J. Alfred Prufrock by T.S. Eliot
“Shall I part my hair behind? Do I dare to eat a peach?
I shall wear white flannel trousers, and walk upon the beach.
I have heard the mermaids singing, each to each.
I do not think that they will sing to me”
