The accent of the characters in the play is almost a clear Beijing movie. Mr. He Qun, the director, considered that eunuchs in Qing Dynasty were all recruited from Hebei (Hejian area), so Mr. Pang, the actor of eunuch, spoke Hebei dialect on the basis of Hejian dialect.
According to historical data, Empress Dowager Cixi hated the timid sounds of other dialects, and eunuchs all entered the palace from childhood, so all eunuchs in the late Qing Dynasty had Beijing accent and Beijing rhyme.
