weather code

Morse code is an on-off signal number, just a communication signal composed of numbers and English.

People will always encounter all kinds of risks in their life, especially those who often engage in outdoor activities. Because of the weather and other reasons, it is also common to be trapped outdoors. At this time, having rich first aid knowledge plays a vital role. Through their own first aid knowledge, quickly get out of the current predicament, so as to achieve the purpose of self-help.

Men dig clams trapped at sea and hit them with flashing headlights? Morse code? Success.

In Xiamen, a man was trapped in the sea because he was digging clams on the beach, so the man flashed a signal with his scalp needle to guide rescuers and was finally rescued. According to the man's own description, he came to the seaside to dig clams at low tide. But I didn't expect the tide to rise so fast at the seaside. So I didn't have time to evacuate, and finally I was trapped on a reef hundreds of meters from the shore. At this time, a patrolman happened to pass by and found the flashing signal light played by the trapped man.

Life-saving knowledge in the field is very important.

It can also be seen from this incident that it is very important to have a wealth of domain knowledge. If the man didn't think of reminding the patrol with headlights, he would probably miss the best rescue time. Having a wealth of self-help knowledge can provide the most important life guarantee for our outdoor travel.

Develop good habits from an early age.

In fact, we should form a good habit of learning life-saving knowledge from an early age, not just life-saving knowledge in the wild. We should learn the daily knowledge of fire prevention and drowning, which can ensure our life safety. At this point, parents should be educated from an early age. For children who have lived by the sea and mountain since childhood, more attention should be paid to safety education. Parents must strictly check to ensure that children can learn useful knowledge in time.
