Is the Tai Ji Chuan practiced by the old people in the park Chen Tai Ji Chuan or Yang Tai Tai Ji Chuan? Does it have practical significance?

Stylistically, Tai Ji Chuan is Chen style, and Tai Ji Chuan is Yang style. Generally, parks focus on health and fitness, mostly on exercise, and there may be experts, but the probability will be very low. You need to keep observing for a period of time to have a good judgment: after observing for many days, it will exercise 1, not only the whole set of shelves, but also spend some time practicing single strokes repeatedly; 2. I like to practice pushing hands when I have boxing friends or disciples; Although these two performances are not necessarily masters, what is certain is that you have some practical experience.
