Women in Hijabs do Wushu Martial Arts

According to a Facebook commentator, they are practicing Modern Wushu, a presentation sport, like Olympic gymnastics. It is one of 3 big areas of Chinese martial arts. The other two are Traditional Wushu, aka Kung Fu, which focuses on non-sportive fighting for self defense; and Sanshou, aka Sanda, which is a kickboxing style. The styles mentioned in the video are Nanquan (southern fist), Changquan (long fist – or northern fist) and Taijiquan (Supreme Ultimate Fist).
