无言独上西楼， 月如钩。 寂寞梧桐深院 锁清秋。 剪不断， 理还乱， 是离愁。 别是一般滋味 在心头。 ——李煜 Crows Crying at Night Mute， mounting west tower alone， I see the hooklike moon. Lonely plane trees lock in the courtyard drear Cold autumn clear. Cut， it won‘t break， Ruled， it will make A mess to wake An unspeakable taste in the heart. Such is the grief to part.
