What is proper letter ending greeting for a letter to a teacher?


In Chinese letter writing there is a phrase "教祺" that can be roughly
translated as "good luck in teaching" and is used exclusively in the letter
ending greeting. Is there a counterpart in Japanese letter writing? Or is
wishing the teacher's health good enough?

Edit: found a [rather long list](http://www.iwate-jh.ed.jp/pfc/pfc01.htm) of
letter greetings and cannot find anything specific to teachers.




The standard formal opening, equivalent to English "Dear Sir/Madam", is 拝啓.
The closing, equivalent to "Sincerely Yours", is 敬具. I don't see why you
couldn't put in the Chinese greeting as well, along with a little explanation.
The teacher might find it interesting/charming, and there's nothing wrong with
a little cross-cultural exchange.
