我陪西瓜过夏天西瓜陪我过夏天
[wŏ péi xī guā guò xià tiān xī guā péi wŏ guò xià tiān]
It reads 'Wo Pei Xigua Guo Xia Tian Xigua Pei Wo Guo Xia Tian' meaning both as 'I accompany watermelon through summer and watermelon accompanies me through summer.' It suggests a mutual companionship with something as simple and cool as a watermelon during hot summer days, showing a peaceful life and pure joy of living.
