Haas, this is different from Wei Hong, the fu jow master who had a school in China town NYC up until recently. This Wei would be in his mid to late 70s by now and Tak Eng is or was his senior until they had a falling out.
I do not know this guy on the rooftop, though interesting against a capoiera practitioner. My guy can be found at
www.fujowpai.com. Also go to Google and type in Tak Eng for his info as the senior to Wai Hong.
Hope this helps. They were a sister school to my Ying Jow master's school in the 80s and 90s (Sigung Leung Shum) along with Frankie Yee's Hung Gar School (Pedro Cepera Yee and Ty Nunez as some conflicting disciples).
Hope this helps.
