How should you start a letter in Chinese? How should you start a letter in Chinese? More specifically, what's the difference between starters such as 尊敬的，亲爱的，and 敬爱的, and in which cases should you use which one?

写信的时候，“尊敬的”、”亲爱的“、与“敬爱的” 有什么分别？

Edit:
I do know that 尊 and 敬 both mean respect, and 亲 means love between friends or family.
"尊敬的": to your boss or leader (the person who has power and you are not familiar with)

"亲爱的": to your mother or lover, etc.

"敬爱的": the person who teach you, guide you, and also care about you or love you. (tutor, teacher, mentor, etc.)
