&Quota; Nanina, get a good night's sleep; It is a song sung by Bulgarian mothers for their little babies. It is evident that in the Sven women's prison where the great Bulgarian director Binka Zhelyazkova filmed two documentaries, the same song was also sung to the babies, with the first one titled "Nani Na"/"lullaby"/ An incredible true story about the prisoner in the prison. Immediately banned, this movie will add another one - "; Li ce i opako"; Or; the light and dark side of things; eight years later, the socialist regime wrongly named the communist regime collapsed in 1989. Unfortunately, Binka Zhelyazkova did not make any other films after 1990 until her death in 2011. She was deeply insulted by the Bulgarian authorities and decided to refuse to film, which was indeed frustrating because all of her films are now evergreen classics.
