The second son of Yang Lu Chan was named Ban Hou. He developed the Yang style to a high degree of fighting skill, so much so that not many people actually wanted to study from him. This is possibly a reason that it is only in the last few years that his style has started to gain many followers. This is Jiang Jian Ye’s TWO DVD series teaching the entire set. As usual the instruction is clear and repeated numerous times. Over four hours of instruction.
