Outdoor activities is different from general city sightseeing, there are always some potential dangers, the following 10 suggestions are about outdoor self-protection, remember these "do not", you can avoid many dangers.

1. Do not wade through the river after a heavy rain on foot with the water level exceeding the crotch. If you have to cross and there is no rope and other river equipment, try to choose the river wide water slow water shallow, the river bottom more gentle place, looking for a large stone held in the arms, against the flow of small lunge, do not lift the foot, stick to the bottom of the river, slowly move across the river.
2. Do not use small steps on the steep slope to go down the slope head-on; this is very easy to fall backwards, and then ride the slide down the hill, very dangerous. You can use the side, deep squat, side leg press (side lunge) type, move down the hill; this is safe and fast.
3. Do not run when carrying a heavy load down the hill, inertia may make you rush down the hill and get injured. If you carry a heavy load, you should walk slowly to reduce the risk of inertia.
4. Don't go up the mountain alone, especially the wild mountain where few people go or not developed, if you must go, you must do a good job of signposting, don't be brave, and return the way you came.
5. Do not let your hiking shoes have mud, plant leaves, water, snow and other substances that reduce the coefficient of friction on the soles; these substances will make your feet slippery and should be cleaned off in time, especially when climbing or walking in the snow.
6. Don't step on the goat path covered by grass and unable to see the reality below; try to cross over or go around; otherwise, you may fall down the slope or into a deep pit.
7. Don't get too close to the front and back of the bush when drilling, the rebounding thorns can easily stab your eyes; remember to bring a sunglass and lower your head to cover your eyes with the brim of your hat, or use a trekking pole etc. to protect your eyes.
8. Do not use dead branches or weeds and other unstressed things to tension climbing; only be able to climb with the pull of rooted branches larger than the thickness of their thumbs.
9. Do not two people holding hands, pulling people from the bottom up, to each other's wrists in hand. And be sure not to pull a person alone, when someone needs to be pulled up, should immediately go to find more people to rescue together, if you can not find others, to find around to be able to withstand the huge weight of the fixed object, binding a good strong rope and then rescue.
10. Do not climb the slope with more debris, ice and snow, easy to slip, and the adjacent team members are too close; to leave more than the usual spacing of 2 people, to prevent the following people are smashed.
