What is the mouth for? speak Hi means happy and energetic. When you put it together, your mouth is high, which means that you are happy when you speak, and you speak enthusiastically, which means a little boasting. There is no shame in saying hello, but you should pay attention to the standards you need to grasp when communicating with others.
