"The Jungle Book" and its sequels are Kipling's most important works. The story takes the orphan Mowgli's experience in the jungle as the main line, describing the thoughts and lives of various animals in the jungle, thereby praising love, bravery, unity, and kindness, and criticizing hypocrisy, cowardice, greed, and cruelty. The author uses fable-like words to make various animals not only able to speak and have cute characters, but also clearly express their personalities; but the story is also reasonable and logical.
