Hung Gar Eight Diagram Pole Demonstration 洪拳- (五郎八卦棍) By Sifu Leo Au Yeung
This is Sifu Leo Au Yeung (Wing Chun fight choreographer for the "Ip Man" movies) in a neat demo video of the ng lung ba gwa gwan (五郎八卦棍), the Hung Ga 5th Brother's 8 Trigram Pole.
Of particular note is the footwork, which has a 1000 year old reputation for delivering deadly power with the long staff.
The form dates as far back as the Song dynasty (960 -1279 AD), when General Yang Wu lang, the 5th son of General Yang Ye, retired from the military and became a monk, devoting his monastic practice to adapting spear techniques to the staff.
(If the music sounds familiar, it's the theme to "Vikings".)
Here is my si gong doing the traditional Tang Fong version:
