It's hard to say which direction it is, because the point is thin, so you can buy a compass.
After opening it, hold it in your left hand, and you will see a red cross on the inner disk. First, facing the door three steps (seven steps) away from it, turn the circular inner disk so that the pointer points to the south. Then the red line in your hand is parallel to the gate in your eyes. At this time, the vertical red line is the sitting direction of your property, and the vertical red line will drown the upper and lower words of Tianchi (the circle of the pointer). Those near the gate are sitting, while those near you are facing.
I think it should be clear, I hope it will help you.
