The ancients said: move with emotion, be clear with reason. Tell people to learn to impress others with emotion, and then reason with words, and you will get twice the result with half the effort. The ancients also said: if you don't understand, you can't understand. If you want to impress others, it is impossible not to talk about feelings, because people are emotional animals. Only by finding emotional appeal, learning to touch others' hearts with true feelings and playing emotional cards can we realize spiritual communication and emotional singing, thus persuading a person efficiently.
