Is it better to practice Taiji more frequently or less frequently?

There are no extremes in Taiji. The essence is in the training method. If the method is not correct, it is no different from ordinary drills with a lot of time spent but relatively little achievement. So it is not a question of practicing more or less frequently but practicing correctly. That is, the central equilibrium must be vertically maintained. Every movement must be disciplined such that the posture is vertically balanced. The principles remain unchanged: there is straightness in a curve and vice versa. There must be constant learning and practice, understanding the principles and the less obvious points. Mastery of this will produce skill naturally. There is no question, therefore of practicing too much or too little but rather of practicing correctly.
