Instructions for use of survival whistle[ Repost]

The survival whistle does not necessarily need to be used in times of distress, for example, to say hello to those in front or behind, determine the approximate distance, determine the approximate direction of the other party's sound source, etc. ． ． ． ． However, there is a problem in this. Sometimes when climbing a mountain, you just blow the whistle. If you blow it too much, no one will think anything of it. When they hear other people blowing it, they don’t want to blow it anymore. They go their own way. At this time, if someone else blows the whistle, Your foot is sprained, or you need help somewhere, or your new donkey is far away from the road and you don’t know where to go. When you blow the whistle and no one responds, you are very anxious because others think nothing happened. I am busy grinding silently and hard, and don’t have much time to deal with it. It’s like the story of the boy who cried wolf.
