The use of survival whistle specifications to survive whistle does not have to be used in times of distress, for example, say hello to the front and back, to determine how far away, to determine the direction of the other party's sound source, and so on.
However, there is a problem in this, that is, when we climb the mountain, we only raise the whistle, blow it up, and everyone does not feel anything. When we hear people blowing, we don’t want to blow it. When the foot is twisted, or where we need help, or the new donkey in the middle encounters the intersection, we don't know how to get there. No one responds when the whistling whistle is very anxious, because other people think that nothing happened to them. It is like the story of a wolf that he is busy and silently hardworking and does not have much work to do.
