Regardless of the advanced degree of the article for the time being, the word "hehe" has become an inertial term on the Internet. There is even the function of terminating unwanted chats. As the saying goes, "Chat ends in hehe". If an exchange or a relationship makes us feel sad and lost, it may be that the way we speak and communicate has caused such an unsatisfactory result. We often don't realize or even think that our way of talking is "violent" and offensive. If we can recall the conversation after an unpleasant communication, we will find that our language often brings pain to ourselves and others. Negative, mocking, preaching, interrupting, judging, ignoring and not responding words bring emotional and spiritual trauma. These unintentional or intentional verbal violence make people become indifferent and hostile, which is more painful than physical harm. Relatively speaking, violent communication is nonviolent communication, which is the Chinese translation of the word NVC, also known as the language of love and the language of giraffe. In nonviolent communication, the famous Dr. Marshall Luxembourg discovered this communication method. According to it, listening to it can make people feel that they are in harmony. And tell people how to communicate with others in a harmless way, and then return to themselves: take good care of themselves and make positive self-evaluation to better avoid the mental harm of "hidden violence" to others.
