Daoan （1） （314-385） Chinese monk of the Eastern Jin dynasty who initially studied under Fo tucheng 佛图澄， and was greatly responsible for the spread of Buddhism during his era， said to have more than five hundred disciples. He was an early developer of precepts in East Asia， and a prolific author/commentator. A sort of chi^d prodigy in terms of Buddhist studies， he began at an early age to write commentaries on the dhya^na sutras that had been translated by An Shigao 安世高， a work which brought him early admiration and numerous disciples. In his commentarial work， Daoan was one of the first to acknowledge the need to break dependence on the translation method of matching the meanings 格义 of Buddhist philosophical concepts with pre-existent Daoist terms， desiring instead the establishment of an independent Buddhist system of terminology. He was deeply concerned about establishing standards of quality for Chinese translations of Indian works， and in line with this aim， created one of the earliest catalogues of Chinese Buddhist scriptures， called the Zongli zhongjing mulu 综理众经目录， popularly known as the Anlu 安录 （An's Catalogue）. Daoan is also credited as being a founder of the Maitreya 弥勒 worship cult， through his custom of gathering with his students before an image of Maitreya and praying for rebirth in Tus!ita Heaven 兜率天.（2） Chinese monk of the Northern Zhou.
