If this art is a blend between Chinese and Okinawan concepts, how is it different from other arts like Kempo ?
Most arts that claim to blend Okinawan and Chinese concepts are primarily Okinawan with a few Chinese “flavors” thrown in. Pyong Hwa Do, on the other hand, is primarily a Chinese art with Okinawan influences added to it. So you might say it is on the opposite end of the spectrum. Won hop loong chuan is a complete Chinese style (not just small elements taken from one), with a few modifications derived from Okinawan concepts.
