La luna (1979)

After his father's death, Joe accompanied his mother, Katarina, to attend an opera performance in Italy, but became addicted to drugs because of loneliness, which made Katarina heartache and accommodated Qiao in all sorts of ways, which led to the development of an abnormal love between the two. Fortunately, under the moral awakening, it didn't make a big mistake. Katarina had to hide it for many years, and Joe's biological father's secret was revealed that in order to reunite his parents, Joe went to find his real father. The director uses Freud's psychoanalysis theory to explain the behavior of the mother and son, believing that all the meaning and abilities of human beings come from the needs of sexual desire, and that the moon is the carrier representing the image of the mother and the female, in order to metaphor the sexual influence of the mother on her son.
