Near water: camping and rest must be selected near the water source, such as close to streams, lakes and rivers. However, camps cannot be placed on river banks or streams. Once a rainstorm or water discharge from an upstream reservoir or flash flood occurs, there is a risk of life. Especially in the rainy season and flood-prone areas. The lee: In the field camping should consider the issue of lee, especially in some valleys, riverbanks, should choose a lee place camp. Also note that the tent door should not be facing the wind direction. The lee is not only for camping but also for fire. Cliff far away: When you camp, you can't tie the camp below the cliff. Once the wind blows on the mountain, you may scrape stones and other objects, causing danger. Close to the village: When the camp is near the village, there is no need to call for help from the villagers. It is even more important when there are no firewood, vegetables, food, etc. The near village is also near the road, facilitating the movement and transfer of the team. Hidden shade: If it is a camp that requires more than two days of residence, in good weather conditions it is best to choose a shady place to camp. If it is under the big tree and the north of the mountain, it is best to look at the sun, not the evening sun. In this way, if you rest during the day, the tent will not be too hot and stuffy. Lightning protection: In the rainy season or in the thunderstorm area, the camp must not be located on high ground, under high trees or on relatively isolated ground. It is very easy to attract lightning strikes.
