Autumn leaves are falling in the cold, and the desolation everywhere makes people sad.
Autumn leaves are falling, swallows are flying, and the eyes are desolate and sad.
The swallows are flying all over the sky, and the eyes are desolate and sad.
The lonely swallow is falling, and the eyes are full of depression.
The swallow's shadow goes with the wind, and the tears of the dead wood have dried. The road is endless and covered with ice and snow.
The eyes are full of desolation and desolation
The leaves of the trees on the high mountains have turned yellow, and the wind in the sky is rustling and the trees are singing.
The above are all made up, you can take your pick.
