There is a magic in some folks magic that say you can 轉角藏影 meaning you can see the guy make a turn to a corner or a pole and the guy become invisible (you cannot find them) which was something that people do to escape from chase in the old days. this is not a real magic, it's sorcery to brainwash or cloud the person chasing and make them clouded and so they cannot "find" you. but then, if you see it all in a camera, you basically see the person is still there, just the person chasing get crazy and fooled by the brainwashing magic and do silly things that lead him to the wrong way and stuff like that...

We don't do that in our lineage, it's not anything good to do to brainwash people...
