Being a huge fan of the Yang family tradition (from The Netherlands), I try to read as much as I can find. Much is written about the life and skills of Lu Chan, his sons and grand sons. However, it seems impossible to find anything on the sons of (respectively) Ban Hou (Zhao Pen) and Shao Hou (Zhen Sheng). Strange, even though they were contemporates of Cheng Fu, of whom thousands of articles can be found!
Does anybody know why nothing is written on these two? Were they not good enough? Did they break with the family?
