I know it's possibly a form of Long Fist, I also know that Wu Yihui taught it in tandem with Liuhebafa. Master David himself is not very sure about it's history, he really didn't care much about history to begin with. He said that Lu Hong is always associated with LHBF, they are taught together. LH can teach someone to fight in 4 months, but after 3 years the LHBF practitioner can beat the LH practitioner. All of LH's moves are already inside LHBF, so it isn't very essential to teach it to our students, though we were taught it early during our time. It has eight sets, and you have to do it both ways, left side and right side. Fighting with it relies a lot on your eyes, and not sensitivity. We have sort of incorporated a bit of sensitivity with it, and you can see that LH form used with the video of Dylan being thrown.
Master David also said that Lu Hong was the name of the one who invented the style, but that seems contradictory so I don't know if it's accurate. He said it's probably as old as LHBF, or maybe even older, again I haven't found any verification about its age.
Master David's Liu Hong Ba Tsu Quan was extensively given to him by Yin T’ien Hsiung, as he was somewhat a disciple of Yin T’ien Hsiung, which Lau Sam Mok was sort of jealous about, because he was also a disciple of Lau. Yin T’ien Hsiung was the classmate of Chan Yikyan under Wu Yihui, but he concentrated his time primarily on mastering LH.
Master David always called Yin T’ien Hsiung the Lu Hong master. Every time Lau's school (Hong Kong Hwa Yu Xinyi Liuhebafa Association) was challenged, it was either Yin T’ien Hsiung or Master David who would face the challengers. If master David loses the challenge, Yin T’ien Hsiung would win as he was undefeated, again I cannot verify.
I'll share two photos now, the family asked me to fix them for the wake and so I scanned and edited them, and here's the finished copies. Not everyone knew that after Bruce Lee died, Master David was the first choice to double him for the movie Game Of Death, but his immigration papers to the Philippines were set and his flight was scheduled 1 to 2 weeks after shooting would have started, so he rejected the offer. The producers got the 2nd guy to finish the movie. These photos were taken sometime before, during, or after the audition (most probably FOR the audition):
