Who knows Yan Su's poem Yesterday, Today and Tomorrow?

Yesterday today tomorrow

How many days are there in a person's life?

Think about a person's life for three days!

Running yesterday, running tomorrow and walking today.

Don't forget yesterday, think carefully about tomorrow and seize today.

I hope tomorrow, today is yesterday, and I am still by your side!

Like a song, the years are like running water, the spring dream is traceless, and the autumn night is lingering!

I hope tomorrow, today is yesterday, and I am still in your heart.

-Yan Su

I hope it helps you.
