飛則勁捷（勁甄定反捷錢葉反說文曰勁強也王逸注楚辭曰捷疾也勁字從力捷字本從人今俗用也）。

When flying, it is swift and agile 飛則勁捷 (勁, fanqie: 甄定 [jìng]; 捷, fanqie: 錢葉 [jié]; the Shuowen says: "勁 means strong"; Wang Yi's commentary on the Chuci says: "捷 means swift"; the character 勁 is written with the radical 力; the character 捷 was originally written with the radical 人, but is now commonly written this way).
