Guess who is undercover. What are the rules of the game?

Who's Undercover \x0d\ Number of players: 7, 1 Undercover, and some onlookers in unknown so. \x0d\ Rules of the game: Six of the seven people present get the same word, and the remaining 1 people get another related word. \x0d\ Everyone can only say one sentence each round to describe the word he got (you can't say that word directly), and if undercover can't find it, you should also give a hint to your compatriots. \x0d\ After each round of description, 7 people voted for the suspected undercover, and the person with the most votes was out. If there are as many as two people, it is to be determined (that is, reserved). \x0d\ If an undercover survives to the last three people, the undercover wins, otherwise the big army wins. \ x0d \ x0d \ If you choose words, you should choose related words, such as beard and eyebrows, pork and beef, etc.
