Just saw the below clip the other day, enjoyed it quite a bit. This is the style I do, although there are some differences from lineage to lineage, and, of course, all the resulting drama!

This is a southern internal style, known under a few different names, such as michuan (obviously a generic name used by several unrelated styles), southern taiji, and, in the Kansas City area, Six Elbows (this name comes from, of course, the six elbows practiced by its practitioners).

In practice, it has some in common with chen style, as well as some common ground with wing chun, different lines either seem to stress one or the other (more bridging and striking vs. more throwing and take downs) or, as in the above, a mix of both. This is not to say the style came from these styles, more than simply is composed of standard kung fu from the era in which it began. As an example of the latter, in KC, there tends to be a focus on sticky hands vs. tuishou, as most of the other kung fu stylists to practice with tended to be wing chun.
