Those distress calls we can’t forget in the wild.

According to their own situation and the surrounding environmental conditions, send out different distress signals.Typically, the three repetitions represent a call for help. Smoke signals Firelight is very effective as a contact signal.Distress can be based on their own situation: in order to ensure its reliability, during the day on the fire put some moss, green branches, rubber and other smoke;In the evening, you can put some dry wood to make the fire burn and raise the fire. Setting off three sets of flames is an internationally accepted distress signal, and placing them in a triangle with equal intervals between each pile is ideal, which also facilitates lighting.If fuel is scarce or you are badly wounded, or if you are too hungry or too weak to make three fires, simply light one. Do not let all signal fires burn all day, but be prepared to keep the fuel dry and light it as soon as any aircraft passes by.The fuel in a fire needs to burn easily and burn quickly when ignited, because some opportunities are fleeting.Birch bark is an ideal fuel.You can use gasoline, but you can’t pour gasoline on a fire.Make a wick with some fabric, soak it in gasoline, put it on a fuel pile, and move the tank to a safe place before lighting it.If the fire burns well after ignition, be sure to add fuel without sparks or embers before adding gasoline. Smoke is a good signal during the day, so add smoke emitting materials to the fire.The smoke rises into the air in sharp contrast to its surroundings and is easily noticed. Bright smoke stands out at night or in dark green jungle.Adding grass, leaves, mosses and ferns creates smoke.Actually any damp thing produces smoke, damp straw mat, cushion can fume burn very long time, fly bug also closes hard at the same time hurtful. Black smoke is most visible in snow or desert.

How did you wash your clothes on the trip

If the hotel is equipped with coin-operated washing machines and dryers, you will be lucky. You just need to coin to buy a bag of washing powder.In case did not sell washing powder, it does not matter, back to the room will Soap rub broken, or take Shampoo, Bath Gel pour in, can also wash fragrant clothes, the effect is better than washing powder. What if you don’t have a washing machine? Ask the concierge first. Is there a cheap laundromat just outside?Or, ask your room attendant if anyone would like to do laundry for you?My experience is that the more backward the place, the more expensive the hotel laundry fees, eat you into the net, eat you helpless — hey, I will ask who is willing to part-time private.On a trip to Hanoi, Vietnam, I spent $5 on a week’s worth of sweaty laundry, but don’t expect them to use an iron. It’s nice and dry. My alternative is to shower (including Shampoo, Bath Gel) while trampling on the clothes (especially effective against undergarments and socks, like a club mallet or washboard).Wait to wash bath, clothings also washed probably, rub with clear water next one rub, jilt one jilt can. The next step is to dry it.Where to hang it?Never hang it out in the bathroom. The humidity is too high.Nor does it work in the clothes-cupboard, which is less likely to dry and smells musty.I suggest: wash out before taking out, as much as possible wring dry, like a roll like wring dry before spreading out.If can’t wring dry clothings, can spread out to put on big bath towel directly (or bedspread, blanket, quilt) go up, roll a roll, let it absorb water (be wicked). Usually, I hang my clothes near the air conditioner (heating) blow dryer or in the air conditioner (heating) area.The trick is to run the clothes through a rope to dry — oh, you must ask, where did I get my rope from?Ah, the nylon rope I brought from home, of course.Remember, but also with a hook, tied at both ends of the rope, convenient suspension.Or hang out of a window so the wind doesn’t blow away. If you don’t have a rope, don’t

Seven golden rules to know when leading a team you only live once.

You only live once!You only live once!You only live once!Many times the life and death of a team lies in the leader’s mind. Life only once, please make “choice”, safety is always the first element of playing outdoors, but also the team leader must master the first element, please always remember: safety is always the first!Safety comes first!Safety comes first! The second golden rule is to respect the weather Bad weather can turn a sunny outing into a terrifying, deadly trip to hell.In the case of the aotai route, 80 per cent of the deaths were linked to changes in the weather. As a team leader, you must judge the weather in time.Sudden changes in the weather may cause the team to lose sight of nothing. The snow and rain may cause the blood of the team members to condense. You seem to lose the ability to think and lose your way. All of a sudden, you feel the pain of death gripping your heart, you feel helpless.You can’t feel your fingers or toes.Ice congealed in your pallor, and you and your companions cried desperately for help in the storm.It’s too late!Don’t put yourself in any of these situations.Read the weather forecasts carefully to make sure you understand them, think carefully about the weather, and be prepared to “camp in place” and “retreat.” Bad weather may happen by chance.Mountains, with their own weather laws, cannot be accurately predicted based on today’s weather conditions. We cannot build a weather observatory on top of the mountain.So the team leader should trust the weather forecast system on the one hand, but pay close attention to the changes in the mountain itself.Place a fixed rope where possible, carry a compass, and the camp must have secure lights.Guard against all possible dangers. The third golden rule is to master the barrel principle The cask effect principle, as most people know, means that how much water you can hold in a bucket depends on the shortest board.If a bucket is to be filled with water, it must have the same level and undamaged board. If one of the boards of the bucket is uneven or there is a hole in the bottom of one of the
