What is the background of the movie Green Book?

The film Green Book is set in the era of severe apartheid in 1960s.

Synopsis: Tony badly needs a job because the nightclub is closed for renovation. A friend suggested that he attend an interview with a doctor of music to find a driver. When I arrived at the luxury apartment, I found that the doctor was a black classical piano player named Tang, and the pianist needed a driver to pick up and drop him off during his southern tour.

Of course, both of them know very well that in the south where apartheid was severe in the 1960s, they could easily get into trouble, but Tony needed money and Tang needed a professional driver who could take care of him. The record company that paid him gave Tony a "Green Book" guide, which listed places where local blacks could eat and sleep, because many hotels and restaurants only served whites.
