Chinese honorifics are words and phrases that indicate social respect or deference in the spoken or written language.
 Especially before the twentieth century, the language used among friends would be very different from that used among strangers such as merchants.
 Although most Chinese honorifics have fallen out of street use since the end of Imperial China, they can still be understood, and indeed occasionally used, by most contemporary Chinese speakers.
 This is partly attributable to the popularity of Chinese historical novels and television dramas, which often employ language from the classical periods.
 In general, language referring to oneself exhibits self-deprecating humbleness, while language referring to others shows approval and respect.
 Honorific language in Chinese was often achieved by using honorific alternatives, prefixing or suffixing a word with a polite complement, or simply by dropping casual-sounding words.
