The latter term, 師父/师父, bears the dual meaning of "master" and "father," and thus connotes lineage in a teacher–student relationship. A tradesperson, for example, would address only his or her own teacher or master in this way; in the previous example, the mechanic's apprentice would address his or her master using this term, but a customer would not address that person in that way. By contrast, a senior religious person—and, by extension, experts in Chinese martial arts—can be addressed either as "master-father" (師父/师父) or simply as "master" (師傅/师傅) in all contexts.
