Piguaquan.

This is an older clip of a performance of piguaquan. Apparently, it is thought that piguaquan and bajiquan were the same art hundreds of years ago, but eventually split into two distinct styles. To me, the similarities of tongbei and pigua are striking.

I also realized that there is a distinct stance in this that is the same as one of the stances the fighter Julia in the Tekken series uses. Just random, useless videogame knowledge lol.

Yes - I definitely see the Tongbei in this, maybe even more than Baji.
