What are the most classic vocals of Cantonese Opera? Pray for the great gods.

On the stage of Cantonese opera, there are three troupes: Gusu, Huizhou, Jiangxi, Hunan, Hunan, Shaanxi and Henan. Yiyang, Kunqu, Qin, Huizhou, Han and Qiyang tunes have been spread and popularized. At present, Cantonese opera vocal music has retained the high-pitched tunes such as Banqiang, Xipi and Furong, Kunqu opera brands and a large number of ditties imported from other provinces, such as Jade Beauty, Cut Flowers, Dressing Table, selling groceries, Eight Bantou and Miss Wang's Fortune-telling. In Banqiang Opera, professional operas such as Papaya Opera, Pagoda Sacrifice Opera, Huilongguan Opera, Jiaozi Opera, Wuer Jiagui Opera, Cave-making Opera and Maizi Opera were successively created, and temple music (Sanskrit) was absorbed, thus enriching the accents of Fan Yi and ice cloud. Among them, Huang Er has the most abundant cavity, including cross, eight-character, long sentence, half, dripping beads, flowing water (second-rate), and inverted music.
