We learn from the passage that pwes………….. .

The most popular national amusement in Burma is the pwe. This entertainment may consist of acting, singing, dancing, clowning or even puppetry. These plays are performed outdoors -most often on moonlit nights. They usually last all night for several nights in succession. The audience sits on reed mats to watch the show. The pwes are free, and more often than not are given by a wealthy individual for the entertainment of his friends and anyone else who cares to attend. The pwe plays are usually legendary tales about princes and princesses and almost always have a happy ending. Actors wear old-time court costumes and proclaim long speeches, but there is always a down to relieve any boredom. Judging by the laughter the clowns provoke, they are found really funny.
