The first part of the clip is Master Zhai with Tony Yang doing the two person kun wu sword fight.
The second part of the clip is what I consider a real benchmark for the flavor of good praying mantis. I don't know the name of the performer but I understand he no longer does praying mantis.
The third part of the clip is Tony Yang doing baji lian huan.
