Many years ago, one of my first teachers, who was a very decent marital artist but unfortunately has passed on, was doing bagua training in his yard similar to what is in the clip.
As he was training he noticed that an elderly lady had stopped her car and was watching him from the road for about 2 or 3 minutes and then drove on - his head was shaven and he wore a decent martial arts top and pants - 10 minutes later the she drove by again and sat there for a good 5 minutes watching him.
20 minutes later - flashing lights and sirens ablaze, the police pulled up and got out of the car, cautiously approaching him.
They ask him to stop, which he did and then they proceeded to move forward.
They asked him, "Exactly what are you doing?" He replied that he was training bagua - they then responded by asking are you okay, are you mentally and emotionally stable? - he then explained that he ran a martial arts school and was training in a system called bagua.
Imagine seeing this from a distance and never hearing of bagua training or for that matter, any martial art:

The officers laughed and said, "Yeah some lady drove by twice and called us to report that some guy, dressed up in crazy outfit kept walking in a circle around a tree for a good 20 minutes or more, and kept changing his arm's positions in a very weird manner. She said she had to report it because that guy seemed to be mentally unstable and just might need help."
They all had a good laugh and then the police left and the teacher continued his training, circling the tree and changing postures.
Imagine someone seeing this from a distance and never having any exposure to martial arts training
