"Double Dance" refers not to dancing, but to dancing, and the training method of "Double Dance" is to make the speech vivid. The so-called "dancing" means adding gestures when talking; The so-called "very happy" means that there is an expression on your face when you speak. The author borrows a dance term and calls these two requirements "duets". When you speak, you are expressionless and don't do any physical movements, which will make the audience feel dull, just like drinking a cup of boiled water.

Albert Merabian, an American psychologist, found that people mainly infect the audience through three aspects when speaking, of which the content of the speech only contributes 7%, the tone, intonation and speed of speech contribute 38%, and body language such as gestures and facial expressions contribute the most, accounting for 55%.

It can be seen that in order to achieve good results in speech, we must not ignore body language, not just move our mouth, but move our mouth, hands and face together. In addition, the effect of the speech should be "pleasant to hear", that is, it can firmly grasp the audience's ears and make them want to listen involuntarily; "Easy to remember" means that the listener can remember your speech naturally without taking notes. "Easy to use"; It's not enough to listen and remember, it's also useful. Tell the truth and be useful.

At present, our family contacts with people, that is, to grasp the "sound, please, three good standards" mentioned in the book, no matter what we say to people, we can have scolding.
