Two-way Display (front and diagonal angle) side-by-side with some minor editing so that you can see the full movement. Enjoy.

The above video has both the Laojia Yilu and Laojia Erlu with three angles:
1. Front
2. Diagonal
3. Back
The back view for Laojia Yilu is also available. It is performed at a different speed and hasn't been included in this video. Great to watch separately to see the form performed with the back view.
