A last tai chi lesson

Our neighbors grandparents Wai Po and Wai Gon are returning to China next week. Wai Gon has been teaching Liam to practice tai chi. Last night Liam received one final lesson before we left.
This time he added five new steps, so that they could go all the way through the full 15 steps.
Liam is always eager to practice tai chi. He is also designing his own martial art form called Chin-adiu. 
Wai Gon is equally eager to teach Liam, too. It’s a wonderful combination to watch. On this last night of practice, the two of them kept at it until I came to get Liam because it was dark at 9 PM!
