I am a long time practitioner and knowing a little about taijiquan, most of the past practitioners (pre-Qing) tended to be labourers, escort police and others of the same lumpenprotelariet (non-examination takers) but interestingly today the vast majority of taijiquan people tend to be engaged in sedentary occupations.
Why don't people like garbagemen, lawn workers, stone masons and others engage in taijiquan?
