Speaking only for myself, I've found it helps me to learn from multiple teachers. While each teacher is different, all share the same basic principles and some explanations work better than others for each student. In addition each student's body and abilities are different.
Amin Wu is one of my favorite teachers. And the BaFa WuBu form is one of my (many) favorite forms. Also doing drills (not to mention yoga) has also helped me immensely as I work to perfect my Tai Chi forms.
So, I invite you all to take a look at Amin Wu's introduction to BaFa WuBu. I think this whole lesson is wonderful, https://www.youtube.com/watch?v=7hkBAD26l6o. She begins teaching the BaFa WuBu at 17:05.
There are many demonstrations of this form on YouTube. Another one, from Shifu Joy, with multiple teaching videos following that I learned a lot from, is at https://www.youtube.com/watch?v=a6Q4ByfeHs4&t=21s.
