What is the first half of nothing?

There is nothing to explain, even nothing to do. Nothing can be done. Describe no achievement.

The source of Tang Bai Juyi's "Send a Whispering in the Night": "If you don't feel white, you can't achieve anything."

The whole poem is as follows:

The hair on the temple is not white, so I can't do anything.

* * * I resigned when I was in my prime, and I stayed in Jiangnan.

I remember the rocks in my mountain spring, but I am familiar with the wind and rain on earth.

The old school will retire first in Hejun and add three schools next year.

In the Tang Dynasty, a man became a doctor. Because my career is not very prosperous, no matter what I do, I often go out for a walk from time to time and want to have some fun. One day, when he arrived at Guo Jing Temple, he was tired of traveling and stayed in the temple. Had a dream at night; In his dream, he walked under a rock and met an old monk. There was a miniature incense burner in front of the old monk, and sandalwood curled up. The old monk said to the provincial official, "The cigarettes in this small incense burner were left over when you made a wish, and now it has become a world of three. You are inspector Jiannan appeasement in the Tang Xuanzong era; In the second year, you were the secretary of Xiqiao in the Xianzong era, and in the third year, you are the current provincial lang official. " After listening to the old monk's words, he suddenly understood a little, as if remembering that all the officials made by III were mediocre and accomplished nothing. So, I don't want to float and sink in the sea of officials anymore, and I seem to suddenly understand life.

In Wang Zhong's poem, there is also a sigh that "if you don't decide what to do, you will accomplish nothing".
