dear mr。wong，re：resignation from the pos to settlement clerki would like to let you know how much i have enjoyed my last three years at the hero company。hero company is an invaluable place for enriching my knowledge about financial field，i enjoyed working with my colleagues and i have learned so much things here。because i would like to take a new challenge and i want to meet people from all walks of life， i have accepted an offer from an insurance firm as a personal financial consultant。
　　i would therefore appreciate it if you would accept my resignation effective from 8 march， 2010.i would be very much obliged if you would kindly give me a reference letter before i leave。
　　thank you for all that you have done to make my work here both interesting and enjoyable。yours sincerely，alexander fung
