This is Southern White Crane. It is believed to be the predecessor to Japanese Goju ryu, as Gogen Yamaguchi had spent much studying and fighting WWII in China.
Apparently this style has its origins in Yim Wing Chun, who while observing a crane fighting. However, this style's power comes from the shoulders, back, arms and qigong, as it is believed that in close quarters, there is not time to use stance or waist power. It specializes in various finger and palm techniques.
