hmmm, I couldn't even find where it said it's Northern kung fu.
A little strange. They are wearing actual karate belts on their "Chinese" style uniforms. People can do whatever they want, but it's a bit odd.
His Weapons Training page says they do "Bo" and "nunchaku", which really suggests Okinawan kobudo. That's an odd combination with Chinese martial arts. Of course Staff methods exist within Chinese martial arts, but to call it "Bo" suggests Okinawan. At any rate, it kinda suggests that this stuff is just filler material, included because people think it's cool and want "weapons training". But the context is all wrong and perhaps his students are ignorant of that fact? It kinda reminds me of all the junky katana that are sold here in San Francisco's Chinatown. it's meant for tourists who don't know the difference and lack the education to understand that a Katana is Japanese, but they are sold as souvenirs all over Chinatown. Kinda odd, when you think about it.
If a genuine kung fu school is going to include weapons training, then it's usually gonna be the traditional Chinese weaponry: staff, spear, sword, saber (dao), butterfly swords, three-sectional staff, guan do (big knife on a staff), chain whip, etc. The fact that he is listing a couple of Okinawan kobudo weapons, and NOT Chinese weaponry makes me think the weapons training is really superficial and not up to snuff. That makes me have doubts about the entire program.
Go check it out, but it's just striking me as a bit odd.
