1, last night's circle is not tonight's circle, and the full moon is twelve degrees a year. You lose your virginity when you get as much as you can. ("Singing the Moon" is anonymous)

2, advise you to cherish youth. I suggest you don't cherish the dress. If you have flowers, you must fold them straight. Don't wait for them to be empty. ("The Legend of the Witch" Don Du Qiuniang)

3, the three-night light is the five-night chicken, which is the time for men to study. Teenagers only know how to play, but don't know how to study hard. When they are old, they regret why they didn't know how to study hard when they were young. ("Persuasion" Tang Yan's true feelings)

("Long Songs" Han Yuefu)
