The correct way to measure that tap, Li Shuanglin.
(1) intersection
The center of the intersection of two roads is called a crossroads. When looking for the first dragon, you can aim the compass at the center of the intersection and measure it. The word pressed by the crosshair near the end of the surveyor is called the first dragon.
(2) T-joint
The measurement method on both sides of the T-shaped road is roughly the same as that at the intersection. After the future dragon is determined, according to the mountain situation, lower the compass at the corner of the road to determine that "the dragon is in the first place".
(3) Three forks in the road
The so-called "fork in the road" is where a road forks, so it is called "fork in the road". For example, a north-south avenue branches off from here and leads to the northwest. At the same fork point, another road leads to the southwest to form a K-shaped road, and the center of the fork is called the "fork".
