麻煩幫我翻譯成簡單英文！thx

During the period when I worked as a salesperson, I have learned some retail sales skills such as showing display, and provide quality service to customers. From the clerical position I held, I have learned word processing, file management, photocopying and handling of general office matters.

(依家d 新型影印機好先進, 分唇(function) 繁多﹐真係要學架)
