Looking for a Bird with Flower Feathers is an unforgettable and beautiful collection of essays written by Bi Feiyu, winner of Mao Dun Literature Prize. This book mainly focuses on describing some creatures in nature, such as red dragonflies, cows and sheep. The three examples listed above are only a small part of the contents of the book, so I think the most impressive content is the cloud in September. This essay mainly talks about the change of September clouds.
