武术
武术 or wu shu is one of the most common/popular forms of martial arts in China. As you can see it is generally practiced in rows of people following an instructor. Commonly it is learned by memorizing combinations of individual movements that in sum constitute sets. Wu shu is also special because it is often practiced with a sword, although not exclusively. I wish I had more time outside of teaching and studying so that I could pick some of it up.
