Dear Sir,

I have learned from that there is a vacancy in your firm, and I wish to apply for the position. I am a graduate of Hong Kong Polytechnics, class of1980. For the last four years I have been working as a salesman for Hong Kong Trading Company, and I am quitting that firm in a few days.
Enclosed you will please find a letter of recommendation from my present employer who likes my service very much but have to let me go, for his firm is going to be closed. While working with Hong Kong Trading Company, I have a good chance to know all the leading chemical product manufactures in this area. My connections built with them in the past may also enable me to get more business for your firm if you will employ me as a salesman. I am sure that these manufacturers would equally welcome my service if I work for you.
I shall appreciate a personal interview at your convenience.

Yours faithfully
