西瓜的爱人叫夏天夏天的爱人叫西瓜
[xī guā de ài rén jiào xià tiān xià tiān de ài rén jiào xī guā]
An interesting play of words translating into 'The Lover of Watermelon Is Called Summer; Summer's Lover Is Called Watermelon', suggesting a reciprocal and intimate relationship as well as indicating that summer is associated with enjoyment such as eating watermelon during that season.
