Many years ago I was in Penang Malaysia (actually, it may have been KL, it was quite a few years ago and I've been to Malaysia many times) - Anyway, I was staying at a hotel that had a fitness suite with a gym and a studio - the studio was empty so I went in there to practice Tai Chi.
After a while a Chinese gentleman came in and said hello and explained that he was a Tai Chi instructor employed by the hotel to give free Tai Chi lessons to guests. He also explained that he had a class starting shortly and that I was welcome to attend. I stayed on and he taught a Tai Chi form that was new to me, the Yang 88 move form.
During my stay at the hotel I had two or three lessons in this form (if I remember correctly) and really enjoyed it. It was a nice form and I missed doing it when I came back to the UK.
Today (Thursday morning, 19th July 2018) I spent two and a half hours training at a class in Wellingborough with a lovely instructor called Dominic Rushmore. He teaches the 88 move form and diary allowing, it is my intention to train with him and to learn the form.
Now, you may be wondering WHY do I, an instructor myself, want to train in something new with somebody else... and here we have one of the key fundamentals of being a good instructor (or perhaps, being good at anything) ... you should NEVER EVER stop learning.
