What's the difference between a master and a teacher?

"Master" and "teacher" both refer to people who impart knowledge or skills in China traditional culture, but in modern society, the meanings and usages of these two words are different.

"Master" is usually used to address people with special skills, such as carpenters, blacksmiths and painters. This word appeared in ancient times, originally referring to the emperor's teacher, and later used as a courtesy title for monks and Taoists. On some occasions, "teacher" can also be used as a title of respect for ordinary teachers, but it is usually more inclined to use the name "teacher".

"Teacher" is a more common title, which is used to address all people who impart knowledge, regardless of their skills and majors. This word may appear later than "master", but it is more commonly used in modern society.

Generally speaking, both "master" and "teacher" can be used to refer to people who impart knowledge or skills, but in specific use, we should choose the appropriate title according to the occasion and context.
