青青河畔草，绵绵思远道。远道不可思，宿昔梦见之。梦见在我傍，忽觉在他乡。他乡各异县，展转不相见。枯桑知天风，海水知天寒。入门各自媚，谁肯相为言！客从远方来，遗我双鲤鱼。呼儿烹鲤鱼，中有尺素书。长能读素书，书中竞何如？上言加餐食，下言长相忆。这首诗最早见于 Green river grass, cotton thinking long way. Far away incredible, dreams of past dreams. I dreamed of dream, suddenly feel in his hometown. He Xiangxiang different counties, exhibition turnaround. Cang Mulberry know the wind, the sea knows the day. Getting started each pro, who willing to speak! Guests from afar, leaving me double carp. Hulu cooking carp, in the scale book. Can read a long book, the book competing for what? On the plus meals, the next words long memory. This poem was first seen
