Tai tou (Chinese: 抬頭, literally "shift head") can be divided into two forms, Nuo tai and Ping tai.
Nuo tai (Chinese: 挪抬, literally "move and shift") is a typographical device used in written Chinese to denote respect for the person being mentioned. It leaves a full-width (1 character wide) space before the first character of the person; it can be represented as Unicode character 3000 (' '). This is sometimes still used in Taiwan for important officials, such as the Late President Lord Chiang Kai-shek and Father of the Nation Dr. Sun Yat-sen, although this practice has gradually fallen out of favor.
Ping tai (Chinese: 平抬, literally "flat shift") is another form. The way to express the respect is to shift the name of person directly to the head of the next line. This is now considered old-fashioned, and when it was used it was usually seen in documents sent between emperor and ministers when the minister mentioned the emperor.
