明月照不尽离人
[míng yuè zhào bù jĭn lí rén]
It originates from traditional Chinese culture where a full moon has often been associated with reunion and separation equally. 'Mingyue Zhaobujin Liren' means 'a bright moon never fully illuminates all parted ones.' The brightness and roundness of a moon always remind people of their loved ones afar; they long for reunion while mourning parting, especially during festivals.
