Here’s a link to a site in Chinese with a few clips of an old school brother of mine that I found recently. He’s apparently started his own school now…
Here’s a page with links to some videos of Baguazhang: http://www.teatime.com.tw/~kungfu/cc9.html
Here’s a page with links to some videos of Xingyiquan: http://www.teatime.com.tw/~kungfu/cc8.html
Sorry I didn’t have time to go through and make a link to each video, but there’s like 10 of them. Just hover your mouse over the underlined characters near the top of the pages and those are the direct links of the videos, right click to save and you’re on your way to being able to view them.
