青梅原来爱竹马竹马原来爱青梅
[qīng méi yuán lái ài zhú mă zhú mă yuán lái ài qīng méi]
It means 'It turns out plum blossoms (a girl) love bamboo horses (a boy), and vice versa'. Derived from an ancient Chinese phrase '青梅竹马' which describes children growing up together since childhood, usually referring to romantic interests developed between two persons from childhood. The nickname humorously depicts reciprocal affection rooted in longtime friendship.
