Insects: Edible insects are: snails, grasshoppers, zhiyi, earthworms, cicadas and so on. It is generally roasted or cooked to eat, so as to avoid parasites in the insect body from entering the human body and causing poisoning or disease.

Plants: There are many edible wild vegetables, wild mushrooms and fruits, such as dandelions, bitters, purslane, amaranth, wild amaranth, hazelnut mushrooms, pine mushrooms, wild fungus, wild chestnuts, hazelnuts, mountain grapes, mountain cherries, hawthorns, hickory, etc.

Making Survival Signal

In addition to SOS, we can also use fireworks signals, but don't cause a fire! Setting off three piles of flames is an internationally accepted distress signal, the fire is arranged in a triangle, the interval between each pile is the most ideal, if the fuel is scarce or you are seriously injured, you can not make up three piles of flames, then light a pile of flames. When the searcher is closer, the hands are greatly waving clothes that contrast with the color of the surrounding environment, expressing the meaning of distress. You should use life straw to drink some water when hungry.

Flag signal should also be mastered, a flag or a brightly colored cloth tied to the wooden stick, when holding the stick movement, on the left side of the long stroke, the right side of the short stroke, increase the amplitude of the action, do the "8" shape movement. If the two sides are closer, there is no need to do a "figure 8" movement. A simple stroke can be done, once on the left side and once on the right, the former should take slightly longer than the latter.

Signal light can be emitted using sunlight and a mirror. Any bright material can be used, such as can lids, glass, glasses, a piece of metal platinum, and a mirror is certainly more ideal. Continuous reflection will regularly produce a long line and a dot, which is a type of Morse code. Even if you don't understand Morse code, casual reflections can be compelling.

Leave a mark: If you get lost in the wild or are in danger, be sure to leave a mark on the place you have been, for example, tie a small red cloth strip to a branch; Fold branches along the way; Discard unnecessary but identifiable personal belongings, etc.

Use of sound: if physical strength allows or if a person is found within the visible range, you can shout for help to attract attention; If you carry a whistle with you, you can also blow the whistle, which saves energy and spreads the sound farther.
