That form begins similarly to our qixing tanglang and echoes it until a few moves after the first turn, but it's very very different from the version we do. That's par for the course - there's a lot of variation.
My master Shi Decheng's qixing tanglang is in our current issue (2010 July/August) - see Shaolin Seven Praying Mantis By Scott Jeffrey. I never learned that form from him. I practice a version I learned from Yan Fei. Yan Fei was from Shandong originally, so he has some root mantis in him, plus he's really long and tall, like so many Shandongers. Our new addition, Yantuo, does a qixing tanglang too. I've seen little bits of it as we use a lot of those lines for our jibengong practice, and his is quite different too. Nevertheless, you can see the root is the same. Unlike some of the more core forms of Songshan Shaolin, qixing tanglang seems to have more variation than the others. They all have variation.
I'm told we're keeping Yanchen on our staff at O-Mei Kung Fu. Three monks, baby, THREE! Plus they're all traditionalists. I saw his guai form last night and I'm thinking I should dust off my old tamo zhang and learn his version. Shaolin life is very good at O-Mei now.
