As bullring’s staff show a banner with the name and weight of the first bull on it, one of the “Alguacilillos” gives the key to the bull’s pens to the “Chulo de Toriles” ( the person in charge of opening the door from which the bull comes out into the ring ). Once the “Areneros” have cleaned the ring and everything is in order, the president taking out the white kerchief, orders the first bull to be released.
After a short sound of the bugles, the door of the bullpen is opened and the bull goes out into the arena.
