Who is the main character in The Other Shore by Gao Xingjian?

Actors playing themselves open and close the play, helping to give the drama its circular movement: the play ends as it begins. When the play opens, a single actor leads the troupe in an exercise with ropes and, as the play ends, the actors reflect upon the play they have just acted in as they leave for their non-theatrical lives. Xingjian originally conceived of The Other Shore as a training piece for actors.
