Self-study at night-the night in the daytime is as cool as water, and you can sit and watch the morning glory and Vega.

Professional course-the sun is like fire, and Noda's rice and grain are burnt by half.

The bell-like a strong wind in spring, blows at night and blows away the petals of ten thousand pear trees.

Final exam-how much sadness can there be, just like a river flowing eastward.
