What's the difference between a maid, a footman and a butler?

A maid is a profession, and her main duty is to do housework for her employer. Some appellations vary from time to time, but the basic nature of work is the same. For example, China was called a handmaid in the old society. maid was a special name for female servants from Victorian England in Japanese subculture, but actually maid or maid servant was also a maid in English. The footmen are the same. Butler originated in France, but the old British court paid more attention to etiquette, details and vanity. According to the court etiquette, the professional concept and scope of duties of butler were strictly regulated, which became the industry standard, and british butler became the classic of domestic service. Therefore, at the beginning of the world-famous British butler, only hereditary aristocrats and aristocratic families with titles could enjoy it, for nothing but royal blood. Deacon, this is a mistranslation of the word "housekeeper" by China people when translating Japanese works. For example, the Japanese cartoon "Black Housekeeper" has also been translated into "Black Deacon". At present, many anime fans think that the word "deacon" in China's vocabulary refers to the "British butler" in a white-collar suit. Actually, deacon China has something to do with the British housekeeper, but his intention is still different. However, in many animation translations, the word deacon has been confused with the word housekeeper, which can be described as "the mistakes of the masses are the truth".
