44.Think twice before you do.
45.Time tries all.
路遥知马力,日久见人心.
46.To save time is to lengthen life.
节约时间就是延长生命.
47.Troubles never come singly.
福无双至,祸不单行.
48.Water dropping day by day wears the hardest rock away.
滴水穿石.
49.When in Rome, do as the Romans do.
入国问禁,入乡随俗.
50.Where there is life, there is hope.
留得青山在,不怕没柴烧.
