When I practice Yilu at the office gym studio, every now and then, I will run into another colleague practicing bajiquan at the same time. I didn't know what bajiquan was, and coincidentally Master Chen posted a video from a bajiquan master not so long ago. It has always been interesting to me having two guys practicing different martial arts in the same room side by side. Today, even more interesting, he actually had an appointment with the taiji instructor, who teaches hunyuan taiji at the office. He is also the teacher, from whom I first learned taiji. Next time, when I run into him, I am sure I'll have a very interesting conversation.
