Ask for a poem about a hairpin and a butterfly. ...

About Baochai catching butterflies: From the 27th episode of A Dream of Red Mansions, the purpose is: Didi Cuiting, Yang Fei, playing colorful butterflies, burying incense graves, flying swallows, weeping and blushing.

Suddenly, I saw a pair of jade butterflies, as big as a round fan, flying up and down in the wind, which was very interesting. Baochai wanted to jump and play, so she took out a fan from her sleeve and jumped down on the grass. I saw that a pair of butterflies suddenly rose and fell, came and went, and was about to cross the river. Baochai led behind, climbed up and down to the Didi Pavilion by the pool, sweating profusely.

Poetry: In order to cherish youth, spring is full of embroidery.

Butterflies that pounce on the bottom of flowers only fly with envy.
