What's the point of making a bow in front of the gate?

In the stress of geomantic omen, if the road is in an anti-bow-shaped way facing your own gate, it is called "the back of the knife" because it looks like a knife, and the health and even life of the householder will be affected. Make a bow opposite the door, and the curved shape of the bow also has this effect. But how much hatred does it have to curse neighbors like this? How can we guarantee that we will not be cursed by other methods after treating our neighbors like this? Remember everything: don't do to others what you don't want them to do to you.
