The poems in Bai Xuege's farewell to Wu Pan palace illustrate the achievements of modern science and technology.

The poem you mentioned in your question, "Suddenly like a spring breeze coming overnight, thousands of pear blossoms blooming on thousands of trees," comes from "Song of White Snow Sending Magistrate Wu Back to the Capital" written by Cen Shen, a frontier poet from the Tang Dynasty. However, this verse is not used to describe the achievements of modern science and technology.

This poem describes the scene of heavy snowfall in the north, vividly showing the magnificent scene of snowflakes in full bloom and as white as spring. The phrase "suddenly like a night" in the poem expresses the sudden falling of snowflakes, while "thousands of trees with pear blossoms in bloom" vividly depicts the accumulation of snowflakes on the branches, just like pear blossoms in bloom.

Although sometimes people use this poem to describe some kind of rapid and grand change, this usage does not come from the original intention of the poem. The original intention of the poem is to describe natural scenes, especially in winter.

If you want to describe the rapid development of modern scientific and technological achievements, you may use some other metaphors or descriptions, such as "explosive development", "changing with each passing day", "advancing by leaps and bounds", etc. These words can more directly express the speed and scale of scientific and technological progress.
