What puzzles me about this is when you speak to a successful salesperson, they will always tell you that the secret to closing a sale is the conversation.

令我困惑的是， 当你与一位成功的销售人员交谈时，他们总是会告诉你， 完成销售的秘诀在于谈话。

They are also good for closing a sale: " If that answers all of your questions, shall we agree on a price" ? The fifth technique is rhetorical questions.

" 如果这能回答你所有的问题，我们能就价格达成一致吗？" 第五种技巧是反问句。
