Dear Mr. Wong,
The day of your (加 "glorious" 如果你確定佢係退休) departure is fast approaching. I would like to take this opportunity to express my most sincere gratitude and appreciation for your giving me a chance to be part of this company. I am also grateful for all the advice and assistance you have given me in the past, which would, I am sure, prove most invaluable in my future career.
Wishing you the best of health and all happiness in the years to come.
I remain
Yours truly,
May Chan
