一若有一问:白云在哪里?答曰:在天上。其实,这答案未必正确。若是乘了飞机,飞到了一定高度,我们就可能说,白云在我们的身边。若是来到一座山的峰顶,我们就会看到白云飘浮在山壑间。再若是用一点科学的眼光看,我们或可以来一点小抒情:白云啊,它还在泥土里,它还在等待阳光,不知哪一天,它会升到天上去……这个问题很有趣, If there is a question: Where is Baiyun? Answer: In the sky. In fact, this answer may not be correct. If we take a plane and fly to a certain height, we may say that the white clouds are on our side. If you come to the peak of a mountain, we will see the clouds floating in the mountains and valleys. And if it is from a scientific point of view, we may come to a little lyric: Baiyun ah, it is still in the soil, it is still waiting for the sun, I do not know one day, it will rise to heaven ... ... This issue is very interesting,
