怎样在野外分辨方向（How to distinguish the direction in the wild）

怎样在野外分辨方向（How to distinguish the direction in the wild） - watch - (must be a pointer watch, which matches the local time) Method 1: 12 means north method: Time is counted in 24 hours. Divide the current time by 2, and the hour of the hour is in the direction of the sun, so the direction of the 12 points on the dial is north. For example, the current time is 16, so the result is 8. So the position of the hour hand at 8 o clock is the direction of the 8 on the dial, which is the north at 12. (I have not yet found out whether this method is common in the north and south hemispheres. Who knows?) Method 2: (northern hemisphere) : the direction of the hour hand in the direction of the sun, the middle line of the Angle between the twelve point scale and the hour hand is in the direction of the south. (since China is located in the northern hemisphere, people are basically Chinese, so this should be more commonly used unless you are a foreigner.) (southern hemisphere) : turn the twelve point scale in the direction of the sun. The middle line between the twelve point scale and the hour hand is in the right direction Method 3: stick with table use: this is the last resort, the watch will be a small stick to the vertical in the middle of the watch turning watch, make the shadow of the sticks with clockwise, the bisector between the hour hand and the 12 hour degrees are from the north! - shadow clock method - Basic conditions: a straight stick that can see the sun Method 1: in the immediate a fair day, looking for a piece of flat land, planted a upright sticks, make its vertical to the ground, to find a stick projection position at this time, marked by small stones at the vertex (vertex a), 15 minutes later, find out the new projection position of the stick, attachment will give you something direction between two points - mark the first point (vertex a) is the west, looking for a wooden stick with this line, vertical to the surface is to the south of the sun! The higher the s
