Taiji practice?

Looked like a kind of taiji practice but I am not really certain.

Got the update that due to the typhoon in China some flights were cancelled or postponed, which also affected some of our summer school students. They would arrive later and this would cause scheduling problem as they are not from the same place.

While my session will be delivered as planned, I do have the online platform for them to review the content throughout the programme. No worries.
