Until the Tang Dynasty, the term "Chánshī" (禅师; Dhyana Master) was regularly used for a monk who was a master of chan, or meditation, versus those who specialized in Dharma (scriptural teachings) and Vinaya (discipline and moral precepts) [REF].
In contemporary China, the term "Chán" (禪), being simply one of many terms for forms of meditation, is not limited to the Chán school alone.
