What are the old students in a group of heroes?

Male characters above middle age are called old pedants, and their typological characteristics are mature, earnest and correct adult males, so old pedants are also called "regular students". They all sing and recite white words in their own voices, basically with three locks of black beard, technically called "black three" In Hero, Zhuge Liang, Lu Su and Liu Bei all belong to such roles.

Hero Club, also known as Jiang Gan's arrest or Jiang Gan's book theft, is a traditional Peking Opera play, which is a "group play" with an old student, a young student, an ugly guy and a complete set of tricks, which pays equal attention to singing, doing, reading and acting.
