Niu Gensheng came to Mengdu Tsinghua Academy to meet Professor Zhu Ziqing, who had not been seen for a long time, and asked him a question, saying: "What is the most valuable thing in this world?" Zhu Ziqing said: "The human brain is the most valuable! Niu Gensheng shook his head and said that it was wrong" Master Ji Xianlin said: "People's fame is the most valuable!" Niu Gensheng said: "Still wrong? Master!" Xu Zhimo happened to pass by and said: "Love is the most valuable!" Niu Gensheng said: "Neither!" Qi Gong also passed by and said: "Human freedom is the most valuable" Niu Gensheng said: "Your answer is close to the truth? But it is not the best answer!" ”

Niu Gensheng came to Suenming Lake and asked Master Wang Guowei, and the master said: "The voice of the prodigal son is the most valuable" Niu Gensheng is still not happy! Niu Gensheng remembered a song: The voice of the prodigal son - Xu Guanjie

It's hard to tell the difference between the real and the fake

There are many dangers and deceitful faces

There is a little shared glory

The water droplets on the eaves are not different

The frog in the well of ignorance wants to add to the price

Empty smug eyes like numbness

Who expected the golden house to turn into a tile

Sometimes it has to happen

There is no time in life to ask for it

What is the use of thunder and wind and rain, how frightened

The heart is fair and flawless

Doing good deeds is the happiest

Sometimes it has to happen

There is no time in life to ask for it

People don't have to worry more than the sand of the sea

You can see the sunset in the sky

The name and interest are like atomization

You can see the sunset in the sky

The name and interest are like atomization

Niu Gensheng was depressed in his heart, he thought that the answer must be easy, but people think that they are smart, and everyone's answer is different! You will have a thousand answers for a thousand people! The answer is different if the dreams of life are different! Liang Qichao said: "The most valuable thing in life is knowledge!"

But some people hid Kejia and said: "Some people are still alive when they die, and some people are born that they are dead! The greatness of life and the glory of death!"

Lu Xun said: "If you don't explode in silence, you will die in silence! Silence is the most valuable thing in gold!" Wang Xiaobo said: "Silent majority, he is willing to be an independent pig, in his mind the pig is the most valuable thing in life! A family can not be a family without a pig! You see that if you want pork for marriage, you can ask a woman in Qinglou to use pork liver as a bubble when you buy pork?

The old man said that time is the most valuable, and Niu Gensheng said that you are half right! Niu Gensheng remembered a song "Where Has Time Gone":

The old tree in front of the door grows new shoots

The dead trees in the courtyard bloomed again

Half survived a lot of words

Hidden in a head full of gray hair

Little feet in memory

Meaty little mouth

Give him love for the rest of your life

Just for that mom and dad

Where has the time gone

I'm getting old before I feel young

Giving birth to children and raising daughters for a lifetime

My mind was full of children crying and laughing

Where has the time gone

Before I could take a good look at your eyes, it was spent

Firewood, rice, oil, and salt for half a lifetime

In the blink of an eye, only the wrinkles on his face remained

Little feet in memory

Meaty little mouth

Give him love for the rest of your life

Just for that mom and dad

Where has the time gone

I'm getting old before I feel young

Giving birth to children and raising daughters for a lifetime

My mind was full of children crying and laughing

Where has the time gone

Before I could take a good look at your eyes, it was spent

Firewood, rice, oil, and salt for half a lifetime

In the blink of an eye, only the wrinkles on his face remained

Niu Gensheng sighed and said: "Time is life, health is the greatest wealth, and people's health and life are the most valuable!" Everyone said that the answer was so simple? It seems that a certain rich man asked the people of the world what the poor lack most? The answer is strange, but the best answer is: "Ambition"! Do the poor have the ambition and resolute perseverance to become rich! The answer to the question must be easy! Do you know? You are rich, and you cannot buy an eternally healthy life? This is the most valuable thing! Do you understand?
