Query: not what i wanted

this book showed much of basic TCM theory with little technics, and technics was not much different than swedish and deeptissue technics. tui na technic vary, some said 12 different techs, some said up to 35 different techs. it would'nt matter how many techs it use as long as it shows how to use different techs and why it use it. how to transit one techs to another techs. this book lacks latter part.
