Reading history is learned, reading history is wise. We can learn from history. Everything in reality can always find their historical shadow, and all kinds of existence in the historical picture can always find their notes in reality. Understanding historical knowledge, summing up historical experience and drawing lessons from history will be of great help to our future work.

Finally, I quote a sentence from Chairman Mao.

He Xinlang studied history.

Apes are different from each other.

Only a few stones have been polished,

Childhood season.

Turn the flame in the copper-iron furnace,

When did you guess?

It's cold and hot.

It's hard to smile in this world,

On the battlefield, we do our best to each other.

It was all over,

Suburban descent.

After reading an article,

But remember, Spotti,

A few lines of history.

The sacred objects of the Five Emperors Huang San,

Cheated the infinite traveler.

How many romantic figures are there?

After the thief became famous,

More Wang Chen stood up and waved Huang Yue.

This song is not finished yet,

Oriental white.
