How to greet a Japanese teacher whose family is sick?

In Japan, when others are sick, they usually use "big events" to express greetings and blessings. Please take care of yourself and express your concern and blessing to each other. In addition, you can also use "O-mimaimoushiagemasu" to show that I have come to see you and express my concern and condolences to the other party. These expressions are common, polite and appropriate.

In Japan, greetings and condolences are very important social etiquette, especially when family members or relatives are ill.
