Fatherly Master Sifu Shi Fu Shifu in Chinese / Japanese...

師父 means master in Chinese (occasionally used in Korean Hanja and Japanese). In the context of Martial Arts, this is the master and teacher who instructs students.

The second character by itself means father. Thus, you get the “Fatherly Master” translation. There's an old Chinese saying that goes something like, “One who is your teacher for one day is your father for life.”

Language notes: I've often seen this romanized as “sifu,” this is actually the Cantonese romanization. In Mandarin Chinese, it's “Shifu.” The pronunciation in Mandarin is actually like “sure foo” (using typical English pronunciation). There's an “R-sound” in there, which is not obvious from the romanization. Many martial arts studios incorrectly pronounce this like “she foo” (which is actually the Japanese pronunciation). In Cantonese, it sounds like “Sea foo” (almost like “seafood,” minus the “d” at the end).

師父 is kind of a weird selection for a calligraphy wall scroll; this entry is more for educational purposes. But you are welcome to buy it if it suits your circumstances.
