Hi Team Lam, I liked and subscribed to your channel. I just have a question, I can do good airchair on my right hand but I can't do it properly using my left hand because my left arm is going to the back. And I have a video comparing my airchair using my right and left hand, can I show it to you so you will see what I'm talking about because I'm practicing my airchair using my left hand for 2 years but it's still the same, my arms is not straight. Thanks!!
