Rough translation:
The thin moon lingers behind the mountain, rising from the sky
The evening wind blows through the catkins, and the man (probably a poet) Blowing the jade flute gently
The white gull swept away, the spring waves were mighty
The man was alone in a small boat, parked quietly by the shallow water
Understanding :
The poet describes what he saw and did when a person was alone in a boat by the water in spring. The words show a peaceful mood, but a faint feeling of loneliness can also be seen. The overall atmosphere of the poem is quiet and the tone Colder
