Wang Bo, who loved to write about ducks, mentions in a fu (a piece of descriptive prose interspersed with verse) how southeast of Zizhou in Sichuan, the Fu River ran through a pool only a few dozen paces around--a hidden place of green cliffs and splashing waves, where lone ducks often settled on the waters, flying up, sinking down, turning and quacking, quite in keeping with their nature.
喜愛以野鴨做文章的王勃，一篇賦裡提到四川梓州東南，與涪江合流處，有不過方圓數十步的水潭，卻清壁絕地，綠波澄天，常有孤鳧棲蕩其間，飛沉翻唼，不違天性。
