I have an out-of-town guest who is looking for a place where she can buy a martial arts book for her son? She says it's "Da Ji", apparently a subset of Tai Chi, or related to Tai Chi. Not sure if that is accurate or not cause I don't think she knows too much about martial arts, and I haven't followed Tai Chi to know enough about it.
Anyway, any recommendations on which place carries a good selection of books on martial arts? She's leaving tonight so anything in the Lower Mainland, please. Thanks.
