How many roads must one man walk down ,before they call him a man .fan yi xia

一个人要走多少路途才算的上是男子汉

一个男人要走路多少路 才能算一个正真的男人.

来源于一首诗歌：
How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before she sleeps in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
How many years can a mountain exist
Before it's washed to the sea?
Yes, 'n' how many years can some people exist
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
上面的“男子汉”什么的都是正确的,引申一下就是人们的认可.
一个人要走多远,才能得到别人的认可?白鸽要飞过多少海洋,才能在沙滩上休息?答案飘荡在风中阿,我的亲爱的朋友.
