提防律師 is a kind of Chinese joke about lawyers.

The first two characters mean “guard yourself against (an attack)” or “beware.”
The last two characters can be translated as lawyer, attorney, or solicitor.

Separately, those characters mean law/regulation/control and master/expert/teacher. Here, you can see the attorney meaning is pretty clear in the individual characters.

Please note this is Chinese only (it won't make sense in Japanese, and the last two characters are sometimes translated together as “Buddhist Priest” in Japanese).

先生 is sensei, which is associated in the west with a master or instructor of karate, aikido, judo, and other Japanese martial arts.

In reality, this is a term of respect for almost any professional or skilled person (doctor, lawyer, teacher, etc.). Sometimes, it is used for musicians and artists who have achieved a certain level of fame, skill, or accomplishment.

It should be noted that this is also a courtesy title in Chinese but more like calling someone “mister” or “gentleman.” It doesn't have the “master” or “teacher” meaning in Chinese - see our Chinese “Master / Sifu / Shi Fu” entry if your audience is Chinese.

In Korean Hanja, this means teacher, instructor, schoolmaster, or schoolmistress.

This entry is for educational purposes. 先生 is kind of a strange thing to put on a wall scroll. It's a title that is used more orally to show respect rather than something written in calligraphy. If you feel it is appropriate in your circumstances, we will create a piece of sensei Japanese calligraphy artwork for you.
