At one time in China there were only male actors. According to one reported custom, the master actor took the virginity of his young apprenticing actors in an unusual and cruel manner. The young actors sat on benches in order of professional rank. On these benches there were round pegs that became progressively larger in size as one moved further up the benches towards the master.
As a young actor progressed in the acting school, he moved up along the benches and was anally penetrated by each peg. At the end, the master himself penetrated the young actor.
