Tai Chi, like many martial arts, was traditionally taught within a specific closed circle – for example often passed from father to son,  mother to daughter,  Master to disciple. Over time, however, this tradtition has slowly been eroded and instead of this small closed circle teaching, Tai Chi has now emerged in public parks all over China.  Unfortunately, this mass interest means that the traditional and original style of teaching and the philosophy of Tai Chi have almost been lost.
