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.
业务办公室的往来信件除内容简明扼要, 主体鲜明外, 不要夹带无关内容。如果您十分清楚所要表达的'事, 也需充分地考虑您所表达重点的开场白, 以避免走题。一旦叙述过的事情, 就不必再重复。往往最后一段重复原有内容会破坏整篇信的效果。
