Dear Isabelle,
Re: Yang forms
I just came back from making some lentil soup. Garlic, extra virgin olive oil, red lentils, ginger, a spot of Encona West Indian hot pepper spicy sauce ... mmmm soup, lentil soooop ...
Looking in my taiji bible [Taijiquan (2004)], I see that Li Deyin covers 81, 24, 42, 42 sword & 32 sword. Of 81 Li Deyin says:
"Yang-style Taijiquan was created by Mr. Yang Luchan (1799-1872) of Yongnian County and refined by his son Yang Jianhou (1839-1917) and completed by his grandson Yang Chengfu (1883-1936) ...
At first, Yang Chengfu set the number of steps of Yang-style Taijiquan as 81, but in his later years he changed the number to 85 by repeating the movement 'brushing aside over the knee in reverse forward stance', dividing the 'turn around to tame the tiger left and right' into the left and right steps, and breaking 'single bian downward' into two movements, 'single bain' and 'push downward'. The rest of the movements remain unchanged. Yang-style has variations such as the forms with 88 steps, 107 steps and 115 steps."
