What's the name of the clothes worn by traditional Wushu practitioners in China?

Duijian shirt (Fuzhou people call Duijian shirt, and Minxi people call it Tang suit). The cover is folded in half with a wide cloth. The cover is usually sewn with a cloth bag, commonly known as a "clothes pocket", with five pairs of buttons on the front. A few people sew copper buttons (knitted buttons, nail buttons and buckles were rare in the old society), commonly known as "front cover". At present, some folk Wushu practitioners still wear "double-breasted shirts" as a symbol of martial arts according to tradition and teacher training.

They said it was a monk's cassock.
