Rat tooth and sparrow horn are synonymous with rat tooth and rat tooth.
From The Book of Songs Zhao Nanxing Lu: "Who said that birds have no horns, why wear my house?" ..... Who said that mice have no teeth, why should they wear me? Lu is a poem in The Book of Songs, the first collection of poems in ancient China. This may be a poem, which records the process of a chaste woman resolutely resisting the hooliganism of someone who has a wife, and praises the indomitable character of the woman. The whole poem consists of three chapters and fifteen sentences, with sharp language, vigorous characters and high style.
The Record of Zhao Nanxing is divided into three chapters. The first chapter is so obscure that the first volume of Poem One by Wang Bai, a poet of the Song Dynasty, asserts that other poems are taken out of context and go astray. In fact, according to cutie's Reading Poems, the first chapter can be understood as the woman's attitude, while the latter two chapters are hypothetical words, "to predict its changes and make extreme remarks" to show determination, and it is not necessarily necessary to sue the government.
