Message in the Letter

A deeper and longer-lasting impression of a message was formed when delivered in a letter, as opposed to receiving the same message online.

与线上接收信息不同的是，人们在写信时对同样的信息的印象会更深刻、更持久。

Other choices, in descending order of personalization, are: a real-time phone call, a voice-mail message, a handwritten note, a typewritten letter, and the most unfriendly is email.

按照私人化程度降序排列，其他选择有：实时电话、语音邮件、手写便条、机打信件，而最不友好的是电子邮件。

Traditional steganography hides its message as, say, every 20th word in a letter, or as the colour of every hundredth pixel in an electronic image.

传统的信息隐藏法隐藏信息的方式是藏掉一封信中的每20个字，或者一幅电子图片中的每百个像素。
