月亮照着你太阳晒着我
[yuè liàng zhào zhe nĭ tài yáng shài zhe wŏ]
'The moon shines on you while the sun tans me' metaphorically indicates the differences or unfairness one experiences. One may have a serene and smooth life (bathed by gentle moonlight), while another struggles under more direct, harsher circumstances (under bright sunshine).
