'They' will accept you if you're a beginner - or on the condition to renounce all prior training if you have martial arts / kung Fu experience.
You're not allowed to train with anyone else while going to this place.
Upon watching some videos of their school, I've concluded that it's not worth renouncing anything. On top of that, I received attitude from the owner.
I wouldn't train at any school that held a philosophy as narrow minded as this.
There are more open-minded & great schools & teachers out there. Keep looking.
