How can the movie Farewell My Concubine have the singing of Kunqu Opera?

The third floor is right. In Farewell My Concubine, Dieyi and Xiao Lou began to give public concerts to Zhang Gong when they were very young. Then Wu Ye asked, "Does Kunqu opera have a bottom?" Moreover, Wu Ye also said that "men are afraid of running at night and women are afraid of thinking" to test the thinking of Butterfly Clothes, and thinking at night is all Kunqu opera. The little nun was twenty-eight years old, and her hair was cut off by the master in her prime. I'm Nv Jiao e, not human. This lyric, which was sung wrongly by Butterfly Clothes for countless times and finally stabbed into the throat by Xiao Lou with a smoking pot, is itself the "Mountain Slope Sheep" qupai of Kunqu Fansili. It's just that in Chen Kaige's movies, it's spoken in the vernacular, but it should be sung!
