Never say die
No cross, no crown
不经历风雨,怎么见彩虹
New wine in old bottles
Never too old to learn, never too late to turn
亡羊补牢,为时未晚
No garden without its weeds
没有不长草的园子
No living man all things can
世上没有万事通
No man can do two things at once
一心不可二用
No man is born wise or learned
没有生而知之者
No man is content
人心不足蛇吞象
No man is wise at all times
聪明一世,糊涂一时
None are so blind as those who won't see
None are so deaf as those who won't hear
No news is good news
没有消息就是好消息
No one can call back yesterday
昨日不会重现
No pains, no gains
没有付出就没有收获
No pleasure without pain
没有苦就没有乐
No rose without a thorn
没有不带刺的玫瑰
No sweet without sweat
No smoke without fire
Nothing brave, nothing have
不入虎穴,焉得虎子
Nothing dries sooner than a tea
