...seem to have many similarities imo. However, I'm no master and my opinion could simply be completely wrong lol. I was wondering if some Xingyi practitioners could point out the major differences between the two styles (obvious ones aside, ex: Ving Tsun has a form named Siu Nim Tao and Xingyi doesn't).

If i could go ahead and ask questions about the stance and movement:

I've read (note: not experienced in person) that the Xingyi basic stance, san ti shi/sher, has most of the body weight on the back leg, about 70/30. I've also heard many people say that it's very similar to boxing. I have a bit of experience boxing (in other words, i cross train it but am no pro) and I personally dont understand how that weight distribution is similar to boxing. Could anyone explain?
