Tibetan opera performance is divided into three parts: the opening drama Arova, the main drama Bear and the auspicious ending drama Tashi. The opening ceremony, also known as Wimbledon or Garuwimba, is mainly to offer sacrifices to the audience, pray for exorcism and introduce the plot. Generally speaking, there are two people present: Jia Lu, seven in Wimba and seven in Ram.

Legend has it that these three characters evolved from the characters in Qu Jie Lausanne. Jaru is a prince, Wimba is a fisherman or hunter, and Ram is a fairy. During the performance, Wimba wore a mask to sing and dance, and then Jia Lu led a group of fairies to sing and dance, so as to introduce the actors, explain the plot of the main play and attract the audience. The performance time is three days and three nights, even six or seven days; As short as two or three hours, it's up to the dramatist.
