It's September 10 again, and teachers are still busy

Only in the "happy"

Another way: hard!

After all,

A teacher is hard to find

Both have to meet it

Thank you when you are precious.

Remember that year

I don't know the end of the universe

Boundary of the sea

How does history climb the mountains of the earth

What you said

Turn the page

Listen to it

With their feet to quantity

Thinking opens the world.
