In 1828, during a visit to Chilbul-am Hermitage 七佛庵 in Jirisan Mountain, Cho-ui transcribed a Ming Dynasty Chinese text on tea. Two years later on his return to Ilchi-am, he produced the ChaSinJeon (or Dasinjeon) (茶神傳 Chronicle of the Spirit of Tea) as a simple guide to the basic principles involved in making and drinking tea. In 1830, he published a now lost collection of his own poems with prefaces and postscripts by four leading scholar-administrators in which they show their personal interest in Seon 禪 Zen practice and the drinking of tea. He then returned to his hermitage, where he wrote and painted. In 1837, he composed the DongChaSong (or DongDaSong) (東茶頌 Hymn in Praise of Korean Tea), at the request of Hong Hyeon-Ju. This is the work for which he is most celebrated among lovers of tea in Korea.
