If we describe the great achievements of the twentieth century, we can use poetry.

The achievements of the 20th century can really be described as "like the strong wind in spring, which blows at night and blows open the petals of ten thousand pear trees".

It can also be described as "not what it used to be, changing with each passing day, shaking the earth."

The image vividly compares the continuous achievements of people in the 20 th century to countless pears that bloom overnight, fast and numerous.

I hope I can help you.
