Writing scenery, the poet was caught in the rain on the way, and his depression was even worse. The flowers on the shore were wilted by the rain, and the partridge stopped screaming at the deserted wild ferry. It's getting late and the tide is receding, but the homesickness is even more turbulent. The poet expresses his feelings in the scenery, touches the scenery, and sets off the poet's sad mood in his journey with sad scenery, which lays the foundation for the whole poem.
