"Swimming in the clear sky, looking for fragrance among chrysanthemums" comes from Tang Geng's Cold Bees Picking Chrysanthemums. Bees suddenly descended from the clear sky, came to the chrysanthemum bushes to look for fragrance, and climbed to the stamens with the sound of "buzzing", even the shadows were blended with fragrance.
The poet chose the moment when the bee fell from the air and began to collect honey, and wrote it vividly, which made the reader seem to see its secret and busy figure in the fragrance.
