Shi Yiguang Xi Shi in Chinese / Japanese...

觀世音 is an alternate title for Guanyin, the Bodhisattva of Compassion or Goddess of Mercy.

觀世音 is the Buddhist bestower of children, the protector of life and all in distress (especially of those at sea).

This is the title for Kyōto city

Kyōto is arguably, the cultural capital of Japan.

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.

西施 is the Chinese title for Xishi, who lived around 450 BC. She was a famous Chinese beauty, perhaps the foremost of the Four Beauties (四大美女). She was given by King Gou Jian of the Yue Kingdom as a concubine to the King of Wu. This was part of an elaborate plan to destroy the Wu Kingdom - and it worked.

Note: In Japanese, this can be an unrelated given name, Seishi. Though the Xishi story is somewhat known in Japan.
