Correspondances from business offices depend so thoroughly on the nature of the concern that little need be said except that they be clear, concise and to the point.
If you know exactly what you want to say and give considerable thought to the initial statement of your most important point you cannot go far astray. And when you have said what you intended to say, stop. A meandering last paragraph can destroy the entire letter.
業務辦公室的往來信件除內容簡明扼要, 主體鮮明外, 不要夾帶無關內容。如果您十分清楚所要表達的'事, 也需充分地考慮您所表達重點的開場白, 以避免走題。一旦敘述過的事情, 就不必再重複。往往最後一段重複原有內容會破壞整篇信的效果。
