People's consciousness depends on the material world, and the sadness you feel when you meet the old people comes from the education you have received, the books you have read, the people you have met and the road you have traveled.

When I was a child, my family told you that it was not easy for grandparents to raise you.

In class, the teacher told you: I am old, and people are old.

When studying, the book tells you: those who give white paper are not responsible for wearing it on the road.

The TV you have watched and the tactile perception tell you that the trip to the avenue is for the public. Old age has its end, and young age has its place.

You know what is right and what is good, and then you can see the wrong and bad times. You will be uneven.

If there is injustice, it will sound, but for most of us, we can't do anything without the courage to cross the North Sea.

So you will be sad, suffering for the elderly, lacking in society and powerless for yourself.

Finally, to borrow a sentence from my predecessors, the most powerful people in the world are those who are good at playing and compassionate.
