The setting is beautiful as is the high quality of the martial technique! I suspect that we may assume from this that ‘Taijiquan’ is considered ‘Halal’ within the faith of Islam – a fact which grants the practitioners a certain enhanced ‘virtue’. In China, Islam (and Muslims) are greatly respected for a) their spiritual purity and b) their martial integrity! Good to see Taijiquan in Iran and the people united in practice!
