有心栽花花不发，无心插柳柳成荫。
Measure for measure.
针锋相对。
Misfortunes never come alone.
祸不单行。
Misfortune tests the sincerity of friends
患难见真情
Money isn't everything
钱不是万能的。
Murder will out
纸包不住火。
Nature is the true law
天行有常，不为尧存，不为桀亡。
Necessity is the mother of invention
需要是发明的动力。
. Never fish in trouble water
不要混水摸鱼。
