Hello. I'm looking at the tai chi pushing hands dvds.
The one with the title "sticking hands" https://ymaa.com/publishing/dvd/tai-chi-symbol-yinyang-sticking-hands seems like an introduction.
Does that mean that its content overlaps a lot with the Tai Chi Pushing Hands DVD 1 https://ymaa.com/publishing/dvd/tai-chi-pushing-hands-dvd-1? I'm wondering if I would be missing helpful info if I skip the "sticking hands" one above..
