What is the content of the poem that Cao Cao said on the boat in the movie "Red Cliff"?

Dan Ge Xing (Part 1)

How about singing while drinking?

Like morning dew, it will be more painful every day.

Generosity should be treated with generosity, and worries will be unforgettable.

How to relieve worries? Only Du Kang.

Qingqing Zijin, my heart is leisurely.

But for the sake of your Majesty, I still ponder it.

Yo yo, the deer roars, eating apples in the wild.

I have a guest who plays the drum, harp and sheng.

It’s as bright as the moon, when can we lift it?

Worry comes from it and cannot be cut off.

The more unfamiliar you are, the more you cross the border, the more useless you are.

We talked about the banquet, thinking about old kindness.

The moon and stars are sparse, and the magpies are flying south.

Walking around the tree three times, what branch can I rely on?

The mountains never get too high and the sea never gets too deep.

The Duke of Zhou vomits food, and the world returns to its heart.
