The line "Luoyang's gossamer threads are hundreds of feet long, and the Yellow River's spring ice is pierced by thousands of pieces" does not use metaphors. It describes the scene of spring. The city of Luoyang (or a specific place in Luoyang) is floating with thin thread-like clouds, while the ice cubes of the Yellow River are like thousands of pieces threaded together, vividly depicting the beginning of the breath of spring. Diffuse, the scene of ice and snow gradually melting.
"Gossamer" is often used to describe the webs made by spider-like insects. Here it may be used to describe the shape of clouds that are as continuous as spider webs. "Baizhang" describes the length and scale of this kind of net, emphasizing its large size. "Spring ice" refers to the ice cubes that begin to melt in spring, while "thousand pieces of ice" describes the size and quantity of these ice cubes, vividly showing the scene where the breath of spring begins to slowly arrive and the ice and snow begin to melt into small pieces. .
